Expert Answer:

Dear Student
The pair of electrons of the outermost shell which are not used in bonding, are known as lone pair electrons. For example, in ammonia the nitrogen atom has five electrons in its outermost shell. The three of which are used in forming single bonds with hydrogen atoms. The other two occupy a filled atomic orbital and constitute a lone pair.
We hope that clarifies your query.
