Interpretation Introduction

Interpretation:

The correct statement for radioactive decay is to be identified.

Concept Introduction:

Alpha decay is a kind of radioactive decay in which unstable an atomic nucleus dissipates excess energy by spontaneously ejecting an alpha particle, which results in a decrease in the mass number by four and atomic number by 2.

Beta decay is a kind of radioactive decay in which a beta particle is emitted from an atomic nucleus resulting in a decrease in the atomic number by one unit. It is not accompanied by a change in mass number.
