Expert Answer
In case of som atoms of the elements, they have stable electronic configuration.
That is their duplet or octate state is achieved.
So they do not take part in any chemical reaction and do not accept or donate electrons.
For example
Helium is in duplet state with electronic configuration 1s2 and the valency of helium is considered as zero.
