Question

Example 12.) The polonium isotope 24Po is unstable and emits a 5.30 MeV alpha particle. The atomic mass of
Pois 209.9829 u and that of He is 4.0026 u. Identify the daughter nuclide and find its atomic mass.
Solution​

Answer 1

Answer:

The polonium isotope 34 (Po)210 is unstable, it emits an alpha particle with energy of 5.30 MeV. The atomic masses of 34(Po)210 and 2(He)4 are 209.9829u and 4.0026u respectively. Then incorrect statement is :-1 daughter nucleus is 82(Pb)206 2 disintegration energy of alpha decay is 5.40 MeV3 mass of daughter nucleus is 205.9745 4 kinetic energy of daughter nucleus is 5.3 MeV
