Question

select the correct answer. 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

Explanation:

The types of orbitals in a principal energy level are determined by the angular - momentum quantum number ($l$). For $n = 2$, $l$ can have values of 0 and 1. When $l=0$, it is an $s$ orbital, and when $l = 1$, it is a $p$ orbital. $d$ orbitals start at $n=3$ and $f$ orbitals start at $n = 4$.

Answer:

D. $s, p$
