What is false for covalent bonds and molecules? (Circle all that apply)
a. Molecules are made of metals and non-metals.
b. Atoms in molecules are arranged so that they are as far apart from each other as possible.
c. Molecules share electrons.
d. Molecules gain or lose electrons.
e. Almost all atoms will bond together to achieve 8 electrons in their valence shell.

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: )

it is stable as it is in group 0 which have full outer shells of electrons
