Question: Where are electrons located in a covalent bond?

context: The idea of covalent bonding can be traced several years before 1919 to Gilbert N. Lewis, who in 1916 described the sharing of electron pairs between atoms. He introduced the "Lewis notation" or "electron dot notation" or "Lewis dot structure", in which valence electrons (those in the outer shell) are represented as dots around the atomic symbols. Pairs of electrons located between atoms represent covalent bonds. Multiple pairs represent multiple bonds, such as double bonds and triple bonds. An alternative form of representation, not shown here, has bond-forming electron pairs represented as solid lines.

question: Where are electrons located with respect to each atom in a covalent bond?
short_answers: shared
between atoms

Answer: A covalent bond is a chemical bond in which electron pairs are shared between atoms. These electron pairs, called shared pairs or bonding pairs, are located in the outer shell of each atom in the bond.
