β -Decay could be thought of as a process where a Neutron decomposes into a Proton and an Electron (although, actually there is an emission of an electron and anti-neutrino ). The proton stays inside the nucleus, while the electron is ejected out.
Thus, there should be an increase in the number of protons by one , thus an increase in the atomic number by one .
Hence, the answer is 7 1 4 N
