Bohr Models – Selected Ans Sodium [11] p + s = 11 e - s = 11 1 st ring = 2 e - s 2 nd ring = 8 e - s 3 rd ring = 1 e - s Carbon [6] p + s = 6 e - s = 6.
The Octet Rule All atoms “want” a full valence shell of e- This makes them more stable, like the Noble Gases, which have 8e-, a full valence shell. For.
