Dear  joseph ,

If we accept the idea that nonmetals like to gain electrons, a logical next question is, "How many?" The simple answer is, "However many more will fit in that energy level." Because of the way that electrons fill up energy levels, a slightly better answer is "however many more electrons are needed to fill the s and p sublevels of that energy level." Usually that means "enough to make a total of eight in the outer shell." This principle is called the octet rule.

The octet rule says that atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell. It is a very useful rule but you should also know that there are many bonding situations where it does not apply.
