Question

what is a covalent bond? a. a bond between two atoms resulting from a transfer of an electron b. a bond between two ions of equal and opposite charge c. a bond between two atoms of very different electronegativities d. a bond between two atoms that is made up of shared electrons

Explanation:

A covalent bond is formed when two atoms share one or more pairs of electrons to achieve a stable electron - configuration. Option A describes an ionic bond (electron transfer), Option B also refers to an ionic bond (oppositely - charged ions), and Option C is more characteristic of an ionic bond when electronegativity differences are large.

Answer:

D. A bond between two atoms that is made up of shared electrons
