The rate at which a collection of the same radioactive atoms will decay depends on:
A) the amount of radio waves falling on the material
B) the amount of light falling on the material
C) the temperature of the material
D) the size of the planet or moon on which the material is located
E) only on internal processes within the atoms; nothing external matters

Question

Quizplus · Accepted Answer

The rate of radioactive decay is determined solely by internal processes within the atoms, specifically the stability of the nucleus and the probability of emitting radiation. External factors such as temperature, light, and radio waves will not affect the rate of decay. The size of the planet or moon may affect the way radiation emitted by the radioactive material is absorbed or detected, but it does not affect the rate at which the atoms decay.
