Which types of orbitals are found in the principal energy level n = 2?

A. s

B. s, f

c. s, d

D. s, p

E. s, p, d

D. s, p

Explanation:

Principle energy levels number of sublevels number of electrons

1 1s 2n² = 2 (1) ² = 2

2 2s 2n² = 2 (2) ² = 8

2p

3 3s 2n² = 2 (3) ² = 18

3p

3d

when an atom has 2 energy level it has 1 sublevel (s) in 1st energy level 2 sublevels or orbitals (s ans p) in second energy.

The total number of electrons accommodate by atoms with n=2 are 10. two electrons in 1s two electrons in 2s and six electrons in 2p.
