Noble gases are inert for a simple reason - Their outer electron shells are already full. Generally, the more empty the outer electron shell, the more reactive the element.
Helium has two(2) electrons, and is thus full, all the other noble elements has eight (8) electrons in it's outer electron shell, so they are also full.
*And krypton is not green, but colorless, and forms white crystals when solid.*

∙ 12y agoNoble gases have a full valence shell and is very stable, so they do not like gaining or losing electrons, which would make them unstable. However, krypton can form compounds with fluorine and xenon can form compounds with oxygen and fluorine.

∙ 9y agoNoble gases are inert and do not form ions. This is because noble gases have a full octet. It does not need to bond and do not need any valence electrons.

However, the noble gases already has eight electrons in their outer shell....:)

Why are noble gases also called inert gases?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements) and are known as inert gases.
Why don't the noble gases react with other atoms?
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
Why do noble gases not bind with other elements?
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
Why are Noble gases inert?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
How do electron configurations of noble gases give them high unreactivity?
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.
The elements that do not ordinarily form compounds are?
Noble gases do not normally form compounds.
Why are noble gases also called inert gases?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements) and are known as inert gases.
Why are nobel gases called inert gases?
Because before about 1950, the noble gases were not known to form any chemical compounds.
Why don't the noble gases react with other atoms?
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
Why do noble gases not bind with other elements?
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
What do all noble (inert) gases have in common?
All noble gases have completely filled orbitals and are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons or form compounds at room temperature.
Explain why the noble gases are relatively nonreactive?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Why are Noble gases inert?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Why do you think the noble gases were among the last of the naturally occurring elements to be dicovered?
Noble gases are chemically inert, they do not form compounds. They are found in trace amounts and hence difficult to be identified.
How do electron configurations of noble gases give them high unreactivity?
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.
What element is least likely to combine with another element for form a compound?
The elements in the family Group 0 - Inert Gases (exc. Radon) will not usually combine with other substances, as this group is highly unreactive. Inert Gases; Helium Neon Argon Krypton Xenon (Radon)
Why noble gases don't bond well with other elements whereas all other elements easily form compounds?
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
