Question

Why alpha and beta particles are not wmitted simultaneously?

Answer 1

Answer:

No, the radioactive nucleus does not emit alpha and beta radiations simultaneously.

Some nucleus emit alpha particles, others beta particles and changes into a new nucleus and to balance the energy, gamma radiations are emitted.

Answer 2

Hiii dude.....

Radioactive elements are classed as either being alpha or beta emitters and cannot be both. Alpha rays are helium ions and result in the nucleus of the given element reducing in mass by 4 a.m.u and changing to a new element. This new element may also be radio-active and could be either an alpha or beta emitter.
