Answer :
Thus, the Beta minus decay of carbon-14 reaction is:
[tex]_{6}^{14}\textrm{C}\rightarrow _{7}^{14}\textrm{N}+_{-1}^0e[/tex] Beta particle
The electron capture equation for the given reaction is:
[tex]_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}[/tex]
Explanation :
Beta minus decay : It is a type of decay process, in which a neutrons gets converted to proton, an electron and anti-neutrino. In this the atomic mass number remains same.
The beta minus decay equation is represented as,
[tex]_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0e[/tex]
(A is the atomic mass number and Z is the atomic number)
Thus, the Beta minus decay of carbon-14 reaction is:
[tex]_{6}^{14}\textrm{C}\rightarrow _{7}^{14}\textrm{N}+_{-1}^0e[/tex] Beta particle
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.
The electron capture equation is represented as,
[tex]_Z^A\textrm{X}+_{-1}^0\textrm{e}\rightarrow _{Z-1}^A\textrm{Y}[/tex]
The electron capture equation for the given reaction is:
[tex]_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}[/tex]
