a. one or seven valence electrons.

Answer 2

Answer:

a) One or seven valence electrons.

Explanation:

If an atom has one valance electron, it would be easy for the atom to lose one electron and acquire a more stable noble gas configuration.

This is because, electron lose enthalpy of an atom is lowest for losing one valence electron.

And,

If an atom has seven valence electrons, it would be easy for the atom to gain one electron and acquire a more stable nearest noble gas configuration.

And this is because, electron gain enthalpy of an atom is lowest for acquiring one electron.
