1.	Explain the rate of disintegration of a radioactive element and the decay constant.
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.
