A covalent bond is best described as Question 1 options: the sharing of electrons between atoms. the transfer of electrons. a bond between a metal and a nonmetal. a bond between a metal and a polyatomic ion.

The answer to your question is "the sharing of electrons between atoms"

Explanation:

Covalent bonding is characterized by the sharing of electrons between two elements.

To form a covalent bond, there must be 2 nonmetals and the difference of electronegativity must be between 0 and 1.7.

Example

               HF = 3.98 - 2.2 = 1.78    Both molecules have a covalent bond.

               Br₂ = 2.96 - 2.96 = 0
