Compared to the charge of proton, the charge of an electron has a) the greater magnitude and opposite sign b) the same magnitude and the opposite sign c) the same magnitude and the same sign d) the greater magnitude and the same sign

the volume increases

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!
