A nucleus AXZ emits an α-particle. The resultant nucleus emit a β+ particle. What will be the respective atomic and mass numbers of the final nucleus? |
Z-3, A-4 Z-1, A-4 Z-2, A-4 Z-3, A |
Z-3, A-4 |
After alpha emission Mass number decreases by 4, atomic number decreases by 2. After β + emission, atomic number further decreases by 1. |
