Noble gases Definition and 21 Threads

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its...

'noble gas' is defined as an atom with its valence shell completely filled to its capacity with electrons. Assuming I take an arbitrary atom ( with its valence shell not necessarily completely filled yet ) and assuming I am either adding electrons to it or removing electrons from it or doing...

Recently I've been recycling lead from old bullets.But everytime I recast the molten lead to an ingot, its surface is oxidized, therefore I am losing lead every single time I reuse it. Are there simple solutions to this without using an atmosphere of noble gases?

Other than Helium do Noble gases with even nuclear spin form superfluids? Is there a simple quantum mechanical explanation why the difference below of the Melting point and Boiling point of the Noble gases is roughly the same value? A yes or no would suffice. From...

Does the noble gases have an atomic radius decrease or increase from halogens?

I would like to ask about a question concerning noble gases. "Nobel gases don't react chemically with other substances." Is this statement about nobles gases completely correct or partially correct? Thank you Self made

Walther Kossel and Gilbert Lewis: "During the formation of a chemical bond, atoms combine together by gaining, losing or sharing electrons in such a way that they acquire nearest noble gas configuration." By what understanding I have so far, and do correct me if I'm wrong, atoms tend to attain...

Hi! I saw something on my lecture notes that I don't really understand. It reads "Rare gases have filled s and p-sub-shells, which leads to a spherically symmetric charge distribution. Since electrons are indistinguishable they take on a common wavefunction. The point is that this results in a...

Is it possible to manipulate a noble gas to produce any line in its emission spectrum for a ? For example, argon produces blue but it also has several lines of red, can one force the argon to emit the red bands?

The way I understand plasma is that is almost a gas except some of the electrons of separated from the nuclei entirely making positively charged. Is there a temperature in which Iron is by definition a gas, and not a plasma? Also, can something like a noble gas become a solid?

People normally talk of electrons performing oscillatory motion when an electromagnetic field is incident on an atom. But, won't the electric field of the E.M. wave cause the nucleus of the atom to vibrate...? . "Note: Here I am talking of isolated atoms, that is atoms of noble gases, and not...

First disclaimer: Xenon trioxide, while not existing naturally, can be created artificially. This question is not like "When did you stop beating your wife?" type. So...I read this compound is explosive. Well, a coke and mentos is also explosive. TNT is too. And then, I wanted to know is...

Why did Mendelev order the elements according to their atomic masses rather than their atomic number? Why did Mendelev not include noble gases in his periodic table?

A partnership of companies known as Plasmerg and Intelligentry have been making some, in my opinion, crazy claims they refer to as a Plasmic Transition Process. Nevertheless my curiosity keeps me honed in on their progress reports. They claim they use a mixture of five noble gasses [ie...

Homework Statement I was going through my past question and answer, I then came across this: "The noble gases have the highest ionization energies in each period". I then wondered why and how the above statement is a reality. How can the above statement be true when the noble gases have...

Hello Forum, Does anyone know where I can find the slater bases for the alkali metal 'np' orbitals and the noble gas '(n+1)p' orbitals, either altogether or individually? I'm a physicist and wanted to know what the standard (or even non-standard) reference is? I know that the...

[SOLVED] why are noble gases, gases? Homework Statement this has bothered me for some time, what determines the density of an element at normal atmoshpheric conditions? and more importantly what determines if a substance at s.t.p is a gas solid or liquid Homework Equations gas...

Homework Statement why do the noble gases stay at a gas state whe almost every other element in the period doesnt? The Attempt at a Solution because the elctrons repel each other? i don't know

Hi, I am a student currently engaged in AP Physics B and AP Physics C, and I am curious as to why it is that most of the Noble Gases exhibit and exist in such a stable state. In AP Chem last year I learned that having a configuration in which the valence shell of an atom has eight electrons...

The noble gases when electrically stimulated emit different visible wavelengths. Can they be combined for a greater variety of coloration?

sorry but this si really hard for me i don't understand these 2 question. Explain why some noble gases such as Xe will form compounds and some such as Ne will not? What kinds of orbital arrangemenets contribute to the bonding in ethene H2C = CH2 thats a double bond i tried and i...
