If polar covalent bonding results in a molecule with a positively-charged end and a negatively-charged end, the molecule is called a. electronegative. b. nonpolar. c. an ion. d. a dipole.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
