Answer:

8, not energetically favourable to release electrons, shells are full so can't gain more.

Explanation:

Remember that all noble gases are free from being involved in reactions as they are stable, all elements strive to be stable, I.E have a full outer shell of electrons, noble gases already do, so don't undergo any reactions, He is the only one with a full shell at 2 by the way :)

Think of NaCl in this way, sodium has 1 electron in it's outer shell, Cl has 7, 1+7 is 8 therefore is a "stable compound"
