Explain the rate of disintegration of a radioactive element and the decay constant.
Answers
Answer:
The rate of radioactive decay, i.e. the rate at which an element disintegrates is measured by counting the number of or -particles emitted per unit time. ... It is found that for any given radioactive element, the rate at which it disintegrates at any instant of time is proportional only to the number of atoms present.
Answer:
Explanation:
Radioactive decay also referred to as the nuclear decline, radioactivity, radioactive disintegration or nuclear disintegration is the method by which an unstable atomic nucleus loses energy in the terms of mass in its rest frame by emitting radiation, such as alpha particles, beta particles with a neutrino.
The decay constant is the proportionality between the size of a radioactive atom population and the rate of decline in population due to the radioactive decline. The relation between the half-life, 1/2T, and the rate of decline is given by T1/2 = 0.693/π.
