MCQ
During a negative beta decay
- AAn atomic electron is ejected
- BAn electron which is already present within the nucleus is ejected
- ✓A neutron in the nucleus decays emitting an electron
- DA part of the binding energy is converted into electron
✓
Answer
Correct option: C.
A neutron in the nucleus decays emitting an electron
c
(c)Negative $\beta - $decay is expressed by the equation
$n = {p^ + } + {e^ - } + {\nu ^ - }$
(c)Negative $\beta - $decay is expressed by the equation
$n = {p^ + } + {e^ - } + {\nu ^ - }$
