What is the reactivity of noble gases in the terms of electrons?

Atoms with eight valence electrons are unlikely to transfer electrons to other atoms or to share electrons with other atoms. As a result, inert gases do not react easily with other elements.

∙ 12y agoIf an element has only one or two electrons in its valence shell, but the valence shell is incomplete (thereby excluding helium), the element is readily capable of forming monatomic cations in its compounds. If the valence shell of an element lacks only one or two electrons of being complete and has a complete inner electron shell (thereby excluding hydrogen), the element is readily capable of forming monatomic anions in its compounds. If an element has a complete outer valence shell, it is unlikely to form compounds at all under most conditions. Elements that do not fall into any of the categories defined above are likely to form predominantly covalent bonds in their compounds.

A complete outer shell usually means 8 electrons, except for a few light elements which only require 2 electrons to have a complete outer shell. So the number of electrons that an atom already has determines the number of electrons it will need to either lose, or acquire, in order to complete the outer shell. An atom that has between 1 and 3 outer or valance electrons can get rid of them, to uncover the inner shell which is already complete (transition state elements are a little more complicated since they have incomplete inner shells, but the idea is very similar, nonetheless). Elements with 4 valance electrons (such as carbon) need to either gain 4 electrons or lose 4 electrons, they can do either. And elements having 5 to 7 electrons will gain the added 3 to 1 electrons needed to complete their outer shell. Elements that already have a complete outer shell will be chemically inert.

Explain why noble gases are unreactive in terms of electron shells?
Noble gases are unreactive because their outermost shell, the valence shell, has a full set of eight electrons.
Is a fluorine a noble gas?
Noble gases are, for all intents and purposes, unreactive - there are a few noble gas compounds but you have to really work at it to convince noble gases to form bonds. Fluorine is an extremely reactive gas, hence it is not a noble gas. It is a halogen - the most reactive halogen of them all.
What is the rectivity of the noble gases in terms of valence electrons?
Noble gases are also known as the inert gases, meaning they don't react because they have a stable octet (eight electrons in their valence shell). They all have eight electrons in their valence shell with the exception of helium because helium is rebel, but they are all nonreactive including helium.
Why are noble gases nonreactive?
This is because they have a complete valence shell.Noble gases are closer to being stable in terms of their electrons than other elements, thus making them less inclined to react with other elements.
Define nonmetal in terms of chemical reactivity?
It tends to become negative ions, it has a high electronegativity and ionization energy. Also, it gains electrons.

Why all noble gases are momatomic gases?
In simple terms they all have the stable octet.
Why is gold considered to be a noble metal though it has only one electron in the valence shell?
In chemistry terms, 'noble' is often applied to describe the inert gases of the 8th group in the periodic table. When applied to gold, it is used in the normal sense; noble meaning 'of a higher station or rank of importance', because of its low reactivity.

What noble gases have the most in common?
Sulfide ion (S2- ion) (and not sulfur element) is isoelectronic with argon

Describe the octet rule in terms of noble-gas configurations and potential energy?
"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of oxygen is [He]2s22p4
Why he2 does not exist .explain in terms of lcaos?
Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
When looking at the periodic table how do the physical and the chemical properties change?
Well all of the metals except mercury are solids, and they are on the left side of the table. Along the stair-steps are the metalloids, which have metallic properties and nonmetallic properties. So those are solids. Nonmetals are solids, liquids and gases at STP (standard temperature and pressure). The right side is mostly gases though, the only solids at STP across the stair step are sulfur and iodine, the rest are gases and solids. in terms of melting and boiling points, they decrease across the table, because gases have very low melting and boiling points and they are more prominent in the right side of the table. Other properties such as malleability and ductility decrease across the table. In terms of Chemical properties, they change according to number of valence electrons... and I'm not sure which ones you want me to mention... In terms of chemical reactivity, groups one and two are the most likely to react, and so is group 17, the rest really depends on the number of valence electrons. So if an element say in the transition metals category, the fewer amount of valence electrons, the better. for nonmetals, they're all pretty reactive if they have like 6 or 7 valence electrons. But noble gases barely EVER react...
Will all elements combine with other elements?
in nuclear fusion i assume it is theoretically possible to combine any elements but in terms of chemical bonding, no some elements ie noble gases are very nonreactive, though the heavier noble gases do form compounds with oxygen and fluorine.
