this is a chemistry term which refers to how electrons are arranged in atoms. Electrons occur in pairs and if two electrons are not used for chemical bonds, they form a "lone pair" of electrons. Lone pairs have a high electron density and can affect the polarity of the molecules they occur in. For example, oxygen has two lone pairs and when it forms water, the molecule behaves like a tiny magnet.

A lone pair is a pair (2) electrons in the outer most electron shell which doesn't make bonds since the orbit has satified it's two electrons. An element wants to have a total of 8 valence electrons and will do so by creating 4 pairs (or up to 4 bonds in most cases).

Sounds like you are referring to a pair of electrons in a Lewis structure diagram.
It reflects the bonding status of the valence electrons

a lone pair is a valence electron pair that's not used to bond with any element

a lone pair(2 electrons) are the extra electrons.....
mostly described in the lewis structure diagram

a pair of electrons which do not participate in bonding.
