Group 0 - chemical properties

Compared to other , the are - they are extremely and do not take part in chemical reactions.

Explaining the inertness of noble gases

The table shows the of some noble gases. All the noble gases have complete outer shells:

helium has only two electrons
the other elements have eight electrons in the outer shell

Element	Electronic structure
Helium	2
Neon	2.8
Argon	2.8.8

Element	Helium
Electronic structure	2

Element	Neon
Electronic structure	2.8

Element	Argon
Electronic structure	2.8.8

When elements react, their complete their outer shells by losing, gaining, or sharing . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive. It also explains why atoms of group 0 elements do not share electrons to form molecules.
