There is one lone pair of electrons on the nitrogen atom.
Two lone pair
1
Four pairs of electrons. Neon has a full octet.
there are three N-H bonds in ammonia and hence ammonia has three bonded pairs of electrons in addition, there is one lone pair of electrons on nitrogen
No lone pairs on the N in the nitrate anion (NO3^-)
There is one lone pair of electrons on the nitrogen atom.

There is one lone pair of electrons in a molecule of ammonia: The single nitrogen atom in the molecule has five valence electrons; one of these is in a covalent bond with each of the three hydrogen atoms; and the remaining two valence electrons from the nitrogen atom constitute a lone pair.
One lone pair. The central atom is N (nitrogen) which has 5 valence electrons. Three of them are shared with 3 hydrogen atoms, leaving 2 electrons (1 lone pair) on the N.
