From Wikipedia,
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 a
dative bond, 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.
