n -alpha particles per second are emitted from N atoms of a radioactive element. The half-life of the radioactive element is

Options

  1. An N ~s
  2. BN n ~s
  3. C0.693 N n ~s
  4. D0.693 n N ~s

Correct answer

C. 0.693 N n ~s

Step-by-step solution

As R= N, n= N , or =(n / N)T_ 1 / 2 = 0.693 = 0.693 N n ~s
