Two lone pair
There is one lone pair of electrons on the nitrogen atom.
No lone pairs on the N in the nitrate anion (NO3^-)
There will be a total of 10 lone pairs of electrons. In NI3, each I will have 3 lone pairs (total of 9) and the N will also have 1 lone pair, for a grand total of 10 lone pairs.

There is one lone pair of electrons on the nitrogen atom.
There are 2 non bonding pairs in a nitrogen molecule
There will be a total of 10 lone pairs of electrons. In NI3, each I will have 3 lone pairs (total of 9) and the N will also have 1 lone pair, for a grand total of 10 lone pairs.
Ammonia NH3 one lone pair on Nitrogen, Water H2O two lone pairs on Oxygen.
The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
3 Lone pairs and one unpaired electron
