Question

Count the number of bonding pairs and the number of lone pairs around the right nitrogen atom in this molecule.

Answer 1

Answer:

In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom

and is sometimes called a non-bonding pair. Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure.

A single lone pair can be found with atoms in the nitrogen such as nitrogen in ammonia , two lone pairs can be found with atoms in the chalogen group such as oxygen in water and the halogen can carry three lone pairs such as in hydrogen chloride.

Hence; from this above concept we can extract that in a nitrogen group ammonia have only 1 pair of lone pair where as 2 bond pairs there are totally 3 bond pair.

This following above concept is for ammonia nitrogen.

FOR NATURAL NITROGEN THAT IS N2:

We have 3 pair of bonds and 2 pair of lone pairs.

Hence we can conclude that for

Ammonia : 2 bond pairs; 1lone pair.

Natural nitrogen : 3 bond pairs ; 2 lone pairs.
