Through which type of radioactive decay does Am-242 become Np-238?

Solutions

Expert Solution

Answer : Alpha decay

Explanation :-

Americium-242 (Am-242) undergoes alpha decay by emitting alpha particles to form Neptunium-238 (Np-238).

Alpha decay is a type of radioactive decay in which an alpha particle (He) ​​​​​is emitted from radioactive substance to become another substance. In this process, mass number of the radioactive element is reduced by 4 and atomic no is reduced by 2 because Helium has mass no = 4 and Atomic no = 2. General expression of alpha decay is

​​​​​Therefore alpha decay of Am-242 is

Hence the answer. Thanks
