Final answer:
An atom with the designation 5p refers to an orbital in the fifth energy level with a p subshell. In the p subshell, there are three orbitals.
Step-by-step explanation:
An atom with the designation 5p refers to an orbital in the fifth energy level with a p subshell. In the p subshell, there are a total of three orbitals. Each orbital can hold a maximum of 2 electrons, so the number of orbitals that can have the designation 5p is 3.
