Question

A common example of `beta-"decay"` is
`""_(15)P^(32)to""_(16)P^(32)+x+y`
Then, x and y stand for
A. electron and nectrino
B. positron and neutrino
C. electron and antineutrino
D. positron and antineutrino

Answer 1

Correct Answer - C
In `beta^(-)` deacy a neutron in the nucleus is transformed into a proton, an electron and an anti-neutrino
`nto P + bar(e)+bar(v)`
So, x and y, stand for electron and anti-neutrino.
