Question

When the number of the valence electrons in an element ‘x’ is 4 or more than 4, does ‘(8-x)’ match with the valency of that element? How many electrons are used to complete the octet?

Answer 1

8 electron need to complete octate

Answer 2

No....

As with 4 valence electron will make civalent bond not ionic...not -4 because it will be really difficult for a nucleus to handle 4 more electrons....not +4 because of nuclear charge....so that molecules exist in covalent bond...with valency 4
