has anyone ever memorized the periodic table?
My old physics professor has it memorized.jonegil said:has anyone ever memorized the periodic table?
ice109 said:i think if you have it memorized it's easier to see the trends
Moonbear said:We had to memorize it when I was in junior high school. :yuck: But, there were a lot less elements on it back then. :uhh:
cyrusabdollahi said:The table is already structured to show trends in orbitals and chemical properties.
It is not necessary since one can readily find it on-line or perhaps print one and put it on the wall. But with time, one can learn the groups, e.g. alkali, alkali earth, halides and noble gases.jonegil said:has anyone ever memorized the periodic table?
Spoken like a true engineer.cyrusabdollahi said:What would be the point in memorizing such useless information? Thats the whole reason why its ordered in a table for you to look up.

hey are you going to reply to my pm?
The second from the last column (group 17) is referred to as the ‘Halogens’.jonegil said:i had never seen that group..halides...it certainly corresponds to the "halogéneos" group in portuguese..(F,CL,Br,I and At) i guess.
that's what i thought; if a physicist/chemist used a periodic table on a daily basis it wouldn't take long to memorize it, but the person probably wouldn't think of it as memorization. memorizing it just for fun sounds like a waste of time though.mrjeffy321 said:Useless, I think not. I use the information on the periodic table everyday and it is not even my field of study.
I do think that there is some value in having portions of the periodic table memorized, just as one memorizes the multiplication tables, but I would not go so far as to advocate memorizing the entire table so that you could recreate it from scratch on a blank piece of paper.
chemestry... or chemystry... or alchymy :tongue2:jonegil said:oh...sorry about the previous blunder...i'm not used to "english chemestry"
shramana said:India. We memorize a lot of useless stuff like log values etc. as well.
ice109 said:you guys don't have calculators that evaluates log?
chaoseverlasting said:We arent allowed to use calculators. Not in high school, not for any tests, not in class, for anything really. I think college is going to be the same to some extent. Vedic/mental mathematics is encouraged (and required actually if you want to pass).
We usually memorize the S/P/D/F block elements with their positions and atomic weights. Radioactive disintegration series. As far as log is concerned, log 2, 3, 5, 7 are memorized, and the "times tables" till twenty.
moose said:ice109, 2, 3, 5, and 7 are chosen because they are the first prime numbers.
chaoseverlasting said:Yeah. You can really simplify calculations and do them a lot faster if you know those log values. It really does make sense.
No, memorizing the periodic table is not necessary for understanding chemistry. While it can be helpful to have a general knowledge of the elements and their properties, it is more important to understand the underlying concepts and principles of chemistry.
Memorizing the periodic table may help with recalling specific elements and their properties, but it will not necessarily make you a better scientist. Being a good scientist involves critical thinking, problem-solving, and understanding how to apply knowledge, rather than just memorizing information.
The time it takes to memorize the periodic table varies for each individual. It depends on factors such as learning style, prior knowledge of chemistry, and dedication to studying. Some people may be able to memorize it in a few days, while others may take weeks or months.
Yes, it is possible to understand the periodic table without memorizing it. The periodic table is organized based on patterns and trends in the elements, so understanding these patterns can help with understanding the table as a whole. Additionally, there are resources available, such as reference sheets and online tools, that can assist with quickly finding specific information about elements.
Some people may recommend memorizing the periodic table because it can be a helpful tool for quick recall of information about elements. It may also be useful for standardized tests or other situations where specific knowledge of elements is required. However, it is not necessary for a deep understanding of chemistry and should not be the sole focus of studying the subject.
