Question

14.americium- 241 is widely used in smoke detectors. the radiation released by this element ionizes particles that are then detected by a charged particle collector. the half-life of am-241 is 432.2 years, and it decays by emitting alpha particles. how many alpha particles are emitted each second by a 5.00 g sample of am-241

Answer 1

Hence, 5.1 * 10^-11 alpha particles is being emitted each second by the sample.

What is half life?

The term half life is the time taken for only half of the original  amount of radioactive nuclides to remain.

Thus, we have that the half life is 432.2 years or 1.36 * 10^10 s.

k = 0.693/ 1.36 * 10^10 s

k = 5.1 * 10^-11 alpha particles per second.
