There are a infinitely growing number of bond pairs between atoms.

ONE!
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.
Yes it does for a fact
Ammonia contains N and H atoms. There are 3 bonding pairs.

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

Dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
The nitrogen atom in ammonia has one unshared pair of electrons.
4 pairs
Lewis Dot Diagram. Most tests and reviews mostly look for simply the Lewis Diagram.
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.
