What kind of bond forms when atoms in a molecule do not share their electrons equally a. an ionic bond
b. a metallic bond
c. a polar bond
d. a hydrogen bond

A polar bond

Explanation:

Ionic bond don't share but one atom accepts electron while the other gives away electron Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive A polar bond deals with the share of unequal electron (I.e. Covalent polar bond) A hydrogen bond is covalently bonded to highly electronegative elements of small atomic size
