In metallic bonding, the electrons A. are unable to move. B. are shared between two single atoms. C. are given to one atom by another atom. D. are in a "sea" around the protons of all the metal atoms.

I think it’s A.

Explanation:

Tell me if it’s wrong sorry, I am only in middle school level science.

is there multiple choice answers?

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: )
