In This post you will get answer of Q.
The electron emitted in beta radiation originates from
Solution:
In beta decay, a beta minus particle $ ({{beta }^{-}}) $ is an electron emission of $ beta $ involves transformation of a neutron into a proton, an electron and a third particle called an antineutrino
$ (bar{v}). $ $ _{0}{{n}^{1}}{{=}_{1}}{{p}^{1}}{{+}_{-1}}{{beta }^{0}}+bar{v}. $
