Question

Discuss the oxidation states in Group 18 eiements.

✓

Answer

The group 18 elements have a stable electronic configuration ns2np6 with completely filled orbitals.
Due to completely filled orbitals and complete octets these elements do not show a tendency to lose, gain or share electrons.
They have zero valency and mostly exist as mono- atomic gases.
Xenon exhibits higher oxidation states, as the paired electrons of the valence shell can be unpaired and promoted to the empty d-orbitals.
The unpaired electrons are shared with fluorine or oxygen atoms to form covalent compounds with higher oxidation states such as $XeF _2, XeF _4, XeF _6, XeO _3$ and $XeOF _6$.
