Solution

The correct option is B $β^{-}$ decay
$C_{6}^{14} ⟶_{7}^{14} N + X$
Since, in this nuclear reaction, there is no change in atomic mass but the atomic number increased by one. It is a feature of $β^{-}$ - decay.
$X \to a β^{-}$ particle.
Thus, the given nuclear reaction is an example of $β$ - decay.

Q. What is

β

-decay? Give an example.

Q. Assertion :

{_{z} X}^{A}

undergoes

2

α

- decays,

2

β

- decays (negative

β

) and

2

γ

-decays. As a result , the daughter product is

{_{z - 2} Y}^{A - 8}

Reason: In

α

- decay, the mass number decreases by

unit and atomic number decreases by

2

unit. In

β

- decay (negative

β

), the mass number remains unchanged and atomic number increaess by

1

unit. In

γ

-decay, mass number and atomic number remain unchanged
