The particles emitted when \( ^{39}_{19}K \text{ decay to } ^{39}_{19}K \) is
gamma
beta
electron
alpha
Explanation
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.
