Question

_____________ is a nuclear process that results in no change in the mass number and the atomic number of a nuclide.

• A. Gamma decay
• B. Nuclear fusion
• C. Alpha decay
• D. Positron emission

Answer 1

The correct option is A Gamma decay

Gamma decay involves emission of electromagnetic waves which are a result of de-excitation of the nucleus. It does not contain any particles.

$\therefore$ Gamma decay is a nuclear process that results in no change in the mass number and the atomic number of the nuclide.
