Which of the following is not equal to 325 cg? a. 3250 mg b. 3.25 x 10 5 µg c. 3.25 g d. 3.25 x 10 -3 kg

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: )
