Lone Pairs Definition:
Pairs of electrons in the outer shell of an atom that are not bonded are called lone pairs.
Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Lone Pairs Notes:
In chemistry, a lone pair represents a pair of valence electrons that are not shared with another atom and is sometimes termed as an unshared pair or non-bonding pair. Lone pairs are present in the outermost electron shell of atoms. Their identification is possible by using a Lewis structure. Electron pairs are therefore named as lone pairs if two electrons are paired but are not used in chemical bonding .Examples are the transition metals. Lone pairs in ammonia (A), water (B), and hydrogen chloride (C). A single lone pair can be found with atoms in the nitrogen group e.g. nitrogen in ammonia, two lone pairs can be found with atoms in the halogen group e.g. oxygen in water and the halogens can carry three lone pairs e.g. in hydrogen chloride.
