Q. Some radioactive nucleus may emit
A) Only one $\alpha,\beta$ or $\gamma$ at a time
B) All the three $\alpha,\beta$ and $\gamma$ one after another
C) All the three $\alpha,\beta$ and $\gamma$ simultaneously
D) Only $\alpha$ and $\beta$ simultaneously
Explanation
(a) No radioactive substance emits both $\alpha$ and $\beta$ particles simultaneously. Some substances emit $\alpha -$particles and some other emits $\beta -$particles, $\gamma -$rays are emitted along with both $\alpha$ and $\beta -$particles
