Question

What happens to electrons when a covalent bond is formed?
O They are shared between the bonded atoms
O They are transferred from one bonded atom to another
O They move to the nucleus of the atom
O They are released by each atom to create a positive charge

Expert Solution

Explanation:

They are shared between the bonded atoms is the correct option.

Atoms share electrons to create a stable molecule in a covalent bond. By exchanging electrons, atoms can reach a complete valence electron shell and improve their stability. Because both atoms hang onto the shared electrons, the sharing of electrons results in the formation of a bond between the atoms. Covalent bonds differ from other types of bonds, such as ionic bonds where electrons are moved from one atom to another, in that they share electrons. Each atom retains its electrons and does not release them to form a positive charge or shift them to the nucleus.
