Question

When nucleus of an electrically neutral atom undergoes a radioactive decay process, it will remain neutral after the decay, if the process is

• A. $\alpha$ -decay
• B. ${\beta }^{\oplus }$ -decay
• C. $\gamma$ -decay
• D. ${\beta }^{\ominus }$ -decay

Answer 1

The correct option is C

$\gamma$ -decay

Since $\gamma$ -particles are neutral, therefore, its decay will not change the charge of atom.
All other particles carry charge, so the nucleus won’t remain neutral.
