Concept explainers
(a)
Interpretation:
The number of Radon-222 nuclei decays per minute has to be given.
Concept Introduction:
In a unimolecular
Where, k is the decay constant.
N is the number of radioactive nuclei decay.
(b)
Interpretation:
The number of radioactive nuclei decay has to be given.
Concept Introduction:
Theradioactive lawstates that the probability per unit time that a nucleus will decay is a constant independent of time. This constant is calledthe decay constant and is denoted by
Radioactive decay law,
Where N is the number of radioactive nuclei remaining after time t.
N0 is the number of radioactive nuclei in initial time.
k is the decay constant.
t is the time required to decay.
