When a neutron is converted into a proton, the process is known as beta decay.

The Beta decay general equation:

_6^{14}C\ \ \rightarrow_{\ \ \ 7}^{\ \ 14}N\ +\ _{-1}^{\ \ 0}e\ +\ \overline{v}\ +Q

\text{ Q - value } = \text{ mass of } ^{14}_{6} C - \text{ mass of } ^{14}_{7} N

Neglecting the mass of electron (_{-1}^{0}e ) and antineutron \bar{v} .

Step 1: Writing the nuclear equation for beta decay

\beta - decay of ^{23}_{10} Ne

^{23}_{10} Ne \rightarrow ^{23}_{11} Na - {_{-1}^{0}e} + \bar{v} + Q

\text{ Q - value } = \text{ mass of } ^{23}_{10} Ne - \text{ mass of } ^{23}_{11} Na

Step 2: Determine the maximum kinetic energy(Q-value) of the electrons

Given that

Mass of ^{23}_{10} Ne = 22.994466 u

Mass of ^{23}_{11} Na = 22.089770 u

\text{ Q - value } = 22.994466 - 22.089770 u

\text{ Q - value } = 0.004696 c^2 u

\text{ Q - value } = 0.004696 c^2 * 931.5 MeV/c^2              \because 1 u = 931.5 MeV/c^2

\text{ Q - value } = 4.374 MeV

Hence, kinetic energy of electron (_{-1}^{0}e ) and antineutron \bar{v} = 4.374 MeV

If \bar{ v } = 0 , then maximum kinetic energy of electrons emitted = 4.374 MeV
