Q.
The electron emitted in beta radiation originates from
BHUBHU 2009
Solution:
In beta decay, a beta minus particle $\left(\beta^{-}\right)$is an electron emission of $p$ involves transformation of a neutron into a proton, an electron and a third particle called an antineutrino $(\bar{v}) \cdot{ }_{0} n^{1}={ }_{1} p^{1}+{ }_{-1} \beta^{0}+\bar{v}$.
