Weblone pair. n. (Chemistry) chem 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. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared pair or 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 …

WebLocalized and Delocalized Lone Pairs. Now, leaving aside the chemical terminology, in simpler words, one pair of electrons can move around, while the other pair cannot. These electrons belong to only one atom – they are localized. The ones that can move around are delocalized – they can be placed on one atom, but it can also be shared ... WebGilbert N. Lewis put forward his definitions of acids and bases in the year 1923. According to this definition, an acid is an electron pair acceptor and a base is an electron pair donor. Therefore, a Lewis acid can be defined as a chemical entity that can accept a pair of electrons from a Lewis base to form a coordinate covalent bond with it.
