Question

drag each tile to the correct box.
match each set of energy sublevels to the principal energy level that contains them.
s sublevel
s and p sublevels
s, p, and d sublevels
third energy level
first energy level
second energy level

Explanation:

Principal energy levels (n) have sublevels where n=1 only has an s sublevel, n=2 has s and p sublevels, and n=3 has s, p, and d sublevels.

Answer:

third energy level → s, p, and d sublevels
first energy level → s sublevel
second energy level → s and p sublevels
