someone pls help me with my chemistry test plsss my teacher changes the questions so I can't search them up. its 21 questions so I have to upload multiple posts but look at my account to get the rest pls.

you need to give more information

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: )
