(i) α-decay of
(ii) α-decay of 
(iii) β--decay of
(iv) β--decay of 
(v) β+-decay of
(vi) β+-decay of 
(vii) Electron capture of
Ans : α is a nucleus of helium
and β is an electron (e- for β- and e+ for β+). In every α-decay, there is a loss of 2 protons and 4 neutrons. In every β+-decay, there is a loss of 1 proton and a neutrino is emitted from the nucleus. In every β--decay, there is a gain of 1 proton and an antineutrino is emitted from the nucleus.
For the given cases, the various nuclear reactions can be written as:
