ONE!
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.
There are a infinitely growing number of bond pairs between atoms.
Ammonia (NH3) has one lone pair of nonbonding 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.
There are three lone pairs present in chlorine atom

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
Ammonia contains N and H atoms. There are 3 bonding pairs.
Ammonia (NH3) has a trigonal pyramidal shape due to its three bonding pairs and one lone pair of electrons around the central nitrogen atom.
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
The nitrogen atom in ammonia has one unshared pair of electrons.
Ammonia (NH3) has one lone pair of nonbonding electrons on the nitrogen atom.
The molecular shape of ammonia is called trigonal pyramidal. It has three bonding pairs and one lone pair of electrons around the central nitrogen atom, giving it a pyramidal shape.

In methane (CH4), the central carbon atom does not have any lone pairs of electrons. Instead, it forms four single covalent bonds with the four hydrogen atoms around it.
A molecule with a central atom having one unshared pair of electrons would have a linear shape. The unshared pair of electrons occupies more space and pushes the bonding pairs closer together, resulting in a linear geometry.
