The particles emitted when \( ^{39}_{19}K \text{ decay to } ^{39}_{19}K \) is
A
gamma
B
beta
C
electron
D
alpha
correct option: a
3919K 3919K.
Since neither the mass number (39), nor the atomic number (19) is affected by the emission,the particles emitted can only be gamma ray, which is not a charge particle, but simply a radiation.
