Complete the foll

a) As one alpha particle is produced so the mass number will decrease by 4 and the atomic number by 2,

Resultant reaction:

b) As fluorine is produced so the atomic number increases by 1, which suggests β-decay and usually β decay occurs with a loss of an antineutrino

c) A similar reaction as the previous one, atomic number decreases by one so β⁺ emission occurs
