MCQ

During $\beta^-$ emission:

✓
A neutron in the nucleus decays emitting an electron.
B
An atomic electron is ejected.
C
A part of the binding energy of the nucleus is converted into an electron.
D
A proton in the nucleus decays emitting an electron.

✓

Answer

Correct option: A.

A neutron in the nucleus decays emitting an electron.

$\beta^-$ emission is due to decay of neutron in the nucleus $n \rightarrow p + e^-$.
