Lone pair

From Biocrawler, the free encyclopedia.

A lone pair is an electron pair without bonding or sharing with other atoms. It often exhibits a negative polar character with its high charge density. It is used in the formation of dative bonds, for example, the creation of the hydronium, H₃O⁺, ion occurs when acids are dissolved in water and it is due to the oxygen atom donating a lone pair to the hydrogen ion.
