คำอธิบาย
A lone pair of electrons is a pair of valence electrons in an atom that are not shared with another atom in a chemical bond, also known as a non-bonding pair. These electrons reside in the outermost electron shell, occupy space, and significantly influence a molecule's shape, polarity, and reactivity, often depicted as dots in Lewis structures.
