Second energy level consists of one "s" sub-shell and a "p" sub-shell. So, in a "s" sub-shell there is only one orbital. Whereas in a "p" sub-shell there are 3 orbitals which are , , and .
Also, each orbital can contain a maximum of two electrons.
Therefore, we can conclude that in total there are four orbitals (one from s and three from p) found in the second energy level.
On the second shell there are two individual subshells: The "s" subshell has only 1 orbital with max. two electrons spinning around; and the so-called "p" subshell has 3 orbitals with max. 6 electrons (2 on each!) In total, there are four orbitals with 8 revolving electrons on the second shell. Hope could help :)
