Answer 6

Yep

Answer 7

So let's look at Na2S

So we know that there are two Na atoms and one sulfur atom.

How many electrons does sulfur need to complete its octet? Octet = 8 electrons.

Remember metals like to lose electrons
Non metals like to gain them.

Answer 8

it has 6 ve so it needs to gain 2
