B)disintegration rate
C)coefficient of decay

Question

Quizplus · Accepted Answer

The term used to describe the rate of decay of a radioactive isotope is its half-life, which is the amount of time it takes for half of the original amount of a substance to decay. The disintegration rate refers to the number of atoms that decay per unit of time, while the coefficient of decay is a less commonly used term that refers to the proportion of atoms that decay per unit of time.
