Final answer:
The probability of a photoelectric interaction increases dramatically as the atomic number increases.
Step-by-step explanation:
True. The probability of a photoelectric interaction increases dramatically as the atomic number increases because the number of collisions with photons increases with brighter light, resulting in a higher number of ejected electrons. For example, if we consider two metals with different atomic numbers, the metal with a higher atomic number would have a higher probability of photoelectric interaction.
