What is the next atomic orbital in the series 1 s , 2 s , 2 p , 3 s , 3 p ? 2 d,3 d, 4 s, 3 f

The answer is 3 d

Explanation:

The series is in s-p-d-f form.

But 3f has lower energy potential than 3d.

Hope it helps.

the link still does not work even when adding it to the url bar

explanation:

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: )
