Complete the following decay schemes.
(a) 226Ra → α +
(b) 19O →
(c)
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
