Metals tend to form while nonmetals tend to form
? cations, anions
? anions, cations

cations, anions.

Metals lose electrons in bonding, so they form cations, which are positively charged.

Nonmetals gain electrons in bonding, so they form anions, which are negatively charged.

a is the answer to this question

explanation:

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!
