We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms.

WHAT DOES LONE PAIR MEAN IN ENGLISH?

Lone pair

In chemistry, a lone pair is a valence electron pair which is 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. Electron pairs are therefore considered lone pairs if two electrons are paired but are not used in chemical bonding. Thus, the number of lone pair electrons plus the number of bonding electrons equals the total number of valence electrons around an atom. Lone pairs are a concept used in VSEPR theory which explains the shapes of molecules. They are also referred to in the chemistry of Lewis acids and bases. However not all non-bonding pairs of electrons are considered by chemists to be lone pairs. Examples are the transition metals where the non-bonding pairs do not influence molecular geometry and are said to be stereochemically inactive.

Definition of lone pair in the English dictionary

The definition of lone pair in the dictionary is a pair of valency electrons of opposite spin that are not shared between the atoms in a molecule and are responsible for the formation of coordinate bonds.
