Sometimes, the ejection of an `alpha`-particle does not completely stabilise the nucleus. In such a case, more `alpha`-particles may be emitted. The `alpha`-decay

Options

A. raises the `n//p` ratio and is often followed by `beta`-emission
B. lowers the `n//p` ratio and is often followed by positron emission
C. raises the `n//p` ratio and is often followed by neutron emission
D. lower the `n//p` ratio and is often followed by `gamma`-rays emission

Answer

a

Explanation

The `n//p` ratio increases in case of `alpha`-decay while decreases during `beta`-decay.
