Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.


However under high temperature and high pressure, krypton and xenon from covalent bonds with fluorine and oxygen.

Why are the noble gases not likely to form compounds?

The noble gases already have their full set of valence electrons. They don't need to share or transfer any of their electrons with other molecules.


Do noble gases readily share their valence electrons?

I don't think noble gasses have valence electrons. They are noble because all their shells are full which makes them not as reactive.


A family of unreactive element whose atoms do not gain lose or share valence electrons?

Noble Gasses.


Do noble gases have the maximum number of electrons in their outer energy level?

Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.


What gases do not gain electrons?

Noble gases


What do atoms other than the Noble Gases have to do in order to become stable?

Atoms gain, lose or share electrons and try to attain noble gas configuration.


The most charateristic property of the noble gases is?

Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.


How many valence electrons do noble gases have?

Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.

What are the families that contain a full octet of valence electrons?

This is the family of noble gases (group 18).


How many electrons are in the outermost energy level of noble gases?

Helium has 2 valence electrons. All other noble gases have 8 valence electrons.


What is the outer shell of the noble gases called?

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
