for covalently bonded |

or more nonmetals) |

| • | Do not
use them for ionic cmpds. |

| • | 1. Count the
total no. of valence electrons |
||||||||
| (the group no. is
equal to the no. of valence |
|||||||||
| electrons). |
|||||||||
| • | if the species is
an anion, increase the no. of |
||||||||
| valence electrons
by the charge on the ion |
