Question

A covalent bond __________.

A) is the sharing of a pair of valence electrons by two atoms

B) is the transfer of a valence electron to an atom that has an unfilled valence shell

C) is always one more bond than the valence number for the pair

D) is a weak chemical bond

E) always forms a crystal salt

Answer 1

A covalent bond is a chemical bond formed when two atoms share a pair of valence electrons, allowing both atoms to complete their valence shells.

Step-by-step explanation:

A covalent bond is a chemical bond formed when two atoms share a pair of valence electrons. This allows both atoms to complete their valence shells. Covalent bonds are stronger than ionic bonds because of the close sharing of electron pairs between the atoms. They can be single, double, or triple bonds, depending on the number of electron pairs shared.
