Question

How is a covalent bond formed? An atom gives one or more of its electrons away to another atom. Two atoms share a pair of electrons in their outer shell. Valence electrons move freely through a set of positively charged ions. Two atoms chemically react to create a single atom of another element.

Answer 1

Answer: Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.

Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.
