ammonia is NH3, therefore there is one side which does not share its pairs and is considered an unshared pair, which in proper terms is called a "lone pair."

A, Nitrogen has 5 valence electrons and in ammonia (NH3) 3 of them bond to hydrogen atoms so there are 2 electrons left over, thus 1 electron pair is unshared.

The nitrogen atom has one lone pair (i.e. pair of unshared electrons).
1. Count up the total number of valence atoms contained in all atoms involved in the molecule.
5 for N + 1 for H (3 times) = 8
2. Draw the structure of the molecule, and distribute these valence electrons into the necessary bonds.
3 N-H bonds accounts fo 6 valence electrons.
2 are left over (from the 8), and so these are your unshared electrons that get assigned to the N. (These 2 electrons make 1 unshared - or lone - pair.)

The nitrogen atom in the molecule has a lone electron pair, and ammonia acts as a base, a proton acceptor. For more information in a concise manner check out the link
