Pretend you are designing a jewelry box that stays closed through the use of magnets. Explain how you would have to set up the magnets in each of the two parts in order for it to be strong enough to stay closed unless pulled apart.

jjj89t'ji; it hink the answer is your mom is not si

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: )
