Uh. I would like to change the topic of my question.

What is the difference between a lone pair and an unpaired electron?

Lone pair = 2 unpaired electrons. Unpaired electron = radical.

There are two lone pairs (on the oxygen) in H3COH and one lone pair on nitrogen in NH3.

There is one unpaired electron (and 3 lone pairs) on Br-

Um, Br- is an ion and would have 8 electrons, in 4 pairs, in its outer shell.

Br is diatomic. If you homolytically cleave Br2 (as in alkane halogenation) you get 2Br-, each with 7 valence elctrons.

Edit: You're right. I didn't mean Br-, but Br dot (Br radical).
