Question

In beta decay, what particles can the nucleus emit?

विकल्प

• An electron or a positron

• Neutrons or alpha particles

• A helium nucleus or a proton

• Gamma rays or X-rays

Answer 1

In beta decay, the nucleus emits an electron or a positron. Beta particles have a very small mass, and their penetrating power is greater than that of alpha particles but less than that of gamma rays.
