Lone pair. In science, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond [1] 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.
A lone pair is an electron pair in the outermost shell of an atom that is not shared or bonded to another atom. It is also called a non-bonding pair. One way to identify a lone pair is to draw a Lewis structure. The number of lone pair electrons added to the number of bonding electrons equals the number of valence electrons of an atom.
Definition. Lone pairs are pairs of valence electrons that are not involved in covalent bond formation and exist independently on an atom. They are an important concept in understanding the hybridization of certain elements and the polarity of covalent bonds.

(b) One of the three bonding pairs of electrons in the ammonia molecule. Boundary lines that enclose equal percentages of each electron cloud have been drawn.
Lone pair definition in chemistry, with examples Lone pair is a set of electrons present in an atom’s valence shell that did not participate in a covalent bond formation reaction; therefore, they are also called the non-bonding electrons.While drawing the molecules’ structure, the lone pair electrons on shown as dots (..) above the atom.
Lone pairs occupy more space around an atom than bonding pairs, affecting molecular geometry. Lone pairs can influence the polarity of a molecule. Each lone pair consists of two electrons. Lewis structures represent lone pairs as dots placed around the atomic symbol.

Lone pair is a set of electrons present in an atom’s valence shell that did not participate in any bond-formation reaction. Since they refuse to bond with the other atoms, they are also called the non-bonding electrons. While drawing the molecules’ structure, the lone pair electrons on shown as dots (..) above the atom.
