Periodic Table Quiz: History, Structure & Trends Explained
The periodic table is a chart organizing all known chemical elements by atomic number, electron configuration, and recurring chemical properties. Dmitri Mendeleev created the first widely adopted version in 1869, arranging elements by atomic weight. Since then, chemists have proposed hundreds of alternative layouts, and the table continues to be updated as new elements are confirmed by the International Union of Pure and Applied Chemistry (IUPAC).

Key Takeaways
- Dmitri Mendeleev, a Russian chemist, published his periodic table in 1869, arranging elements by atomic weight and chemical properties.
- Researchers estimate that at least 700 alternative periodic table designs have been proposed since Mendeleev’s original version.
- The International Union of Pure and Applied Chemistry (IUPAC) is the body responsible for approving new elements and assigning their official names and symbols.
- Elements are grouped into categories such as alkali metals, alkaline earth metals, transition metals, metalloids, halogens, and noble gases, each sharing distinct chemical behaviors.
- Periodic trends, including atomic radius, electronegativity, ionization energy, and electron affinity, follow predictable patterns across rows and columns of the table.

What Is the Periodic Table?
The periodic table is a tabular arrangement of the chemical elements, organized by atomic number, electron configuration, and recurring chemical properties. Elements appear in order of increasing atomic number in horizontal rows called periods and vertical columns called groups.
Who Created the Periodic Table?
Russian chemist Dmitri Mendeleev created the periodic table in 1869. Mendeleev organized elements by increasing atomic weight and by shared chemical properties, and his arrangement laid the foundation for the modern periodic table used today.
How Are Elements Arranged in the Periodic Table?
Elements in the periodic table are arranged in order of increasing atomic number, which is the number of protons in an atom’s nucleus. Rows, called periods, correspond to the number of electron shells an atom has. Columns, called groups, contain elements that share similar chemical behaviors because of similar electron configurations.
What Are the Different Groups in the Periodic Table?
The periodic table is divided into several groups, including alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, and noble gases. Each group displays distinct chemical properties and reactive behaviors.
Why Is the Periodic Table Significant in Chemistry?
The periodic table is fundamental to chemistry because it provides a framework for understanding and predicting the properties and behaviors of elements. It helps chemists understand chemical reactions, bonding patterns, and trends in element properties across periods and groups.
How Is the Periodic Table Updated?
The periodic table is updated whenever new elements are discovered or synthesized. The International Union of Pure and Applied Chemistry (IUPAC) approves the addition of new elements along with their official names and symbols.
What Are Periodic Trends on the Table?
Periodic trends are patterns in element properties that appear consistently across the periodic table. These trends include atomic radius, electronegativity, ionization energy, and electron affinity. Understanding these trends allows chemists to predict the properties of elements and the compounds they form.
Are There Different Versions of the Periodic Table?
Yes, different versions of the periodic table exist, each designed for specific purposes. These include the standard periodic table, electron configuration tables, and other specialized versions that highlight particular chemical properties or relationships between elements.
Frequently Asked Questions
When was the periodic table first created?
Dmitri Mendeleev, a Russian chemist, created the first widely recognized periodic table in 1869. He organized the known elements by increasing atomic weight and grouped them according to shared chemical properties, a structure that became the basis for the modern periodic table.
How many versions of the periodic table have existed?
At least 700 alternative periodic table designs have been proposed within the 100 years following Mendeleev’s original 1869 version. These alternative layouts arrange elements differently while still reflecting their chemical properties and relationships.
Who decides when a new element is added to the table?
The International Union of Pure and Applied Chemistry (IUPAC) approves new elements once they are discovered or synthesized. IUPAC also assigns each new element its official name and chemical symbol before it appears on the standard periodic table.
What determines an element’s position on the periodic table?
An element’s position is determined by its atomic number, which is the number of protons in its nucleus. Elements are placed in order of increasing atomic number across periods (rows) and grouped into columns (groups) based on shared electron configurations and chemical behavior.
What are periodic trends?
Periodic trends are recurring patterns in element properties observed across the periodic table, including atomic radius, electronegativity, ionization energy, and electron affinity. These trends help chemists predict how elements will behave and react with one another.
Is there only one correct periodic table layout?
No, the standard periodic table is the most widely used layout, but chemists have created other versions for specific purposes, such as electron configuration tables. Each version organizes the same elements to emphasize different properties or relationships.

9/12
Some guesses panned out fine – others didn't
lol. I'm a chemist and I got 7/12.
What is the name of 114th element in the periodic table?
Congratulations β you have completed Periodic Table Quiz.
You scored 8 points out of 12 points total.
Your performance has been rated as Competent.
For most of the incorrect responses, #4, #9, #11 – did not have sufficient information to make a correct selection. Probability did not land in my favor.
For #6, the info seemed present but not to the point of selection of the correct answer. The kind of question I intend to focus on to improve problem-solving skills.
So 1 to 2 semi-guess / estimates that turned out correct. #2 and #7.
6 correct responses from high level of certainty of knowledge. #1, #3, #5, #8, #10, #12.
6 at most and doing it again right after that results in only 3 or 4, something really wrong with my mind. I really love to work with those who could reach up 8-12 :nb)

9/12.
4 out of what? Hmmh
“I missed year of periodic table, first element synthesized, and which letter wasn’t in the periodic table.”
Ha, ha, I beat you in this area. It’s J.
But for the other answers? Flunked many of them :oldlaugh:
“Apparently people didn’t read the did you know? The date for the first periodic table by mendleev is given before you take the quiz =P
”
D’oh!!
I may not read ‘Did You Know’s, but I do read all the comments in a thread.
I was making a mental note to complain specifically about #8 – I thought it was too hard – either you know it or you don’t. Did not realize it was the easiest of all! :oops:
Well played. Well played.
8/12. I actually missed one question (#9) without realizing it. Guessed at several.
7/12. I made mistakes in the historical ones. I didn’t know a solitaire helped to organise the periodic table…
Why is Lawrencium an Actinide? Shouldn’t numerology place it as a transition metal?
A 10/12 .
4 correct no guess.
4 educated half guesses turned out correct
2 complete guess turned out correct.
More luck than brains, as they say.
“I am not so sure about whether Np or Fr is more rare in nature. Np is produced by neutron capture by Uranium. The neutrons stem from spontaneous fission of Uranium. With this hindsight, also the answer “90” in question 1 is more convention than fact.”
I suppose we would also have to consider the Neptunium released into the environment due to nuclear explosions. ([URL=’http://en.wikipedia.org/wiki/Neptunium#Occurrence’]see this[/URL])
“And what is the correct answer to 10 (the only letter not in the periodic table)? I can’t think of an element with J nor Q within the symbol.”
This is just a guess, but perhaps that question was inspired by temporary element names like Ununquadium, and so the answer must be J.
However that name has been replaced by Flerovium ([URL=’http://www.iupac.org/news/news-detail/article/element-114-is-named-flerovium-and-element-116-is-named-livermorium.html’]see here[/URL]), after the Russian laboratory (whose name in turn was inspired by the physicist Georgy Flyorov) that discovered it in 1998.
And what is the correct answer to 10 (the only letter not in the periodic table)? I can’t think of an element with J nor Q within the symbol.
“I’m not sure #9 is correct given that you give ununoctium as a potential answer. Whereas there are maybe only a few ounces of francium, there have probably been only a handful of atoms of Uuo ever made (though Fr might be the better answer given that there probably isn’t any Uuo on Earth at the moment, and according to the IUPAC, Uuo has not been discovered yet).”
Good call, I’ll correct it

That’s strange because there are 12 total questions. I missed #4 (what did Mendeleev base the periodic table on) and #9 (rarest element). I correctly guessed on #8 (date of the periodic table).

7/12… XDI was wondering, wasn't Astatine the rarest element on Earth?
6/12 from a Finance guy.
Congratulations β you have completed Periodic Table Quiz.You scored 12 points out of 12 points total.Your performance has been rated as Unbeatable.please make corrections.. Hydrogen is in s-block and Helium is in p-block.
Yeah, i agree with you.H – in s-blockHe – in p-block
It seems to me that the lightest of all metals is solid Hydrogen, that is, when pressures are high enough, and temperatures are low enough as we see in the cores of gas giants Jupiter and Saturn. When pressures are low, and temperatures are high, all metals become a liquid, and then (in the extreme) a gas. The lightest solid metal at normal temperatures and pressures is certainly Lithium, but that's not what the question asks, is it?
I got 10 out of 11.
4/12 no guessing here, eh
Haha, just got 4 out of 10. I need to review the table or else my science teacher will get mad at me xD
8/12 and I tutor chemistry at college level……hmmmm
Which element begins with Q?
I scored 11 out of 12. I answered number 11 a little too quickly – shoulda thought it out (silver is Ag). I only scored high because science is bit of a fetish with me, plus some time ago I downloaded Freshny's Periodic Table, an app that can be studied off-line http://download.cnet.com/Periodic-Table-freshney-org/3000-2054_4-10803643.html I highly recommend it to any Chemistry student or aficionado.
You scored 5 points out of 12 points total.Your performance has been rated as Just Passed. hehe
As far as I am concern Helium is in p block .
12/12 Unbeatable
Got 9. The three I got wrong were the historical ones. Why clutter your head with ephemera?
I got 11/12. Good to see that my General Chemistry sequence was not in vain. ;)
One small gripe: a lessor is someone who leases. Try lesser. Btw, Mendeleev almost lost primacy over a mistranslation of periodic into German. Google “fontani mendeleev periodic mistranslated russian”
9/12. Two were educated guesses. I’m ashamed to say I didn’t get the year Mendeleev proposed the table even though it’s written at the top, as a previous poster noted. The other two I got wrong were the first artificial element and the rarest element.
Congratulations β you have completed Periodic Table Quiz. You scored 8 points out of 12 points total. Your performance has been rated as Competent. I guessed on a lot of the questions.
Apparently, people didn’t read the “Did You Know?” The date for the first periodic table by Mendeleev is given before you take the quiz. =P Trick Questions OP
I’ll have to get my #1 son the ChemE to answer, I always thought that the table wasn’t logical and or missing pieces. I was right 40 years ago. So is the first composite Carbon/Carbon made for the nose cone and leading wing edges of the shuttle a top secret? Composites come out these days for hail-proof car panels, fishing poles, and tennis rackets; could they withstand the heat of re-entry?
9/12. Had to guess at three and got all of them wrong: the Solitaire question, the number of actinides, and the year for the periodic table.
6. With two lucky guesses, I picked “J” because I knew it was the youngest of the letters in the alphabet, or so I’ve read.
I know it’s not in the answer choice list, but Astatine is the rarest naturally occurring element. Just an FYI.
There is also a question of what is meant by ‘nature’ (per the question of how many elements exist in nature). 1) Smartass observation: People are part of nature. 2) Wouldn’t a supernova temporarily produce elements even beyond what people have created (possibly reaching a theorized island of [relative] stability)? At any given moment (spatial hypersurface) in the universe, I would presume far more than 90 elements exist (without recourse to assumptions about intelligent aliens).
I am not so sure about whether Np or Fr is more rare in nature. Np is produced by neutron capture by Uranium. The neutrons stem from spontaneous fission of Uranium. With this hindsight, also the answer “90” in question 1 is more convention than fact.
I thought it should be J, since that letter is not used in Latin. But then I chose Q.
7/12
I missed year of periodic table, first element synthesized, and which letter wasn’t in the periodic table.
I got 9, and since I haven’t looked at or thought about a periodic table in at least 10 years, I am quite happy.
What other scores did members get?
