A chemical bond formed when two atoms share one or more pairs of electrons with each other. Double bond: A covalent bond consisting of two pairs of electrons. Electronegativity : A numerical method for indicating the relative tendency of an atom to attract the electrons that make up a covalent bond.
Answer: When atoms share one pair of their valence electrons, a single covalent bond is formed between the atoms. Atoms that share two or three pairs of electrons form covalent double bonds or covalent triple bonds, respectively.
