Which statement about radioactive decay is correct?a. During alpha decay, the mass number remains constant.b. During beta decay, the atomic number remains constant.c. During alpha decay, the atomic number remains constant.d. During beta decay, the mass number remains constant.

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.

Explanation

Reason for the correct option:

The definition of ‘beta particle’ states that 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 any change in mass number. Thus, there will not be any change in mass number.

Hence, option (d) is correct.

Reasons for the incorrect option:

Option (a) is incorrect because it states that during a nuclear reaction, the mass number remains constant...
