Quick student answer

Which of the following best describes a covalent bond?

Direct answer

A covalent bond is formed when two atoms share a pair of electrons.

Key terms

  • Covalent bond: A chemical bond formed by the sharing of a pair of electrons between two atoms.
  • Shared electron pair: Two electrons that are simultaneously associated with two different atoms, constituting the basis of a covalent bond.

Common trap

Confusing covalent bonds with ionic bonds: Clarify that covalent bonds involve shared electron pairs, whereas ionic bonds involve electron transfer leading to charged ions.
