A covalent bond is best described as (A) a bond between two polyatomic ions.(B) a bond between a metal and a nonmetal.(C) the sharing of electrons between atoms.(D) the transfer of electrons.(E) a bond between a metal and a polyatomic ion.

Option C. the sharing of electrons between atoms

Explanation:

Covalent bond is a type of bond in which the reacting element share their valence electrons in order to attain the noble gas configuration.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
