Atomic numbers = number of protons and also = number of (a)
Energy levels are also called (a)
The first electron shell can hold up to a maximum of (a)
The second energy level can hold up to (a)
The third energy level can hold up to (a) (The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it. But when the third level contains 8 electrons, the next 2 electrons go into the fourth level.)
The (a) rules states that atoms tends to gain or lose or share up to 8 electrons
