Lone pairs and bonding pairs
Explanation:
The electron domain around the central atom includes
- All lone pairs on the central atom
- All bonding pairs between the central atom and the atoms directly attached to it
Double and triple bonds count as single domains.
Thus, the nitrite ion has three electron domains:
- A lone pair
- An N-O single bond
- An N-O double bond
