Question

(I seriously don't understand what this questin means, please don't delete need all the help i can get)

Answer 1

I've always been told that it's eight. This is only because the atom has to have the saem protons (positively charged) neutrons and electrons (negatively charged). However this does not occur with all atoms. :)

Answer 2

Every atoms which are not charged must have equal number of protons & electrons.

In short, Your Answer would be 8

Hope this helps!
