Which of the following statement is true when a gamma decay occurs from the nucleus of an atom?
- A Mass number is reduced by 4 and atomic number is reduced by 2
- B Mass number is reduced by 4 and atomic number remains the same
- C Mass number remains the same and atomic number increases by 1
- D Mass number and atomic number are not changed
Answer & Solution
Correct Answer
(D) Mass number and atomic number are not changed
Step-by-step Solution
Detailed explanation
Gamma decay involves the emission of high-energy electromagnetic radiation, known as gamma rays, from an excited nucleus to a lower energy state. During this process, the nucleus does not lose any protons or neutrons. Consequently, the number of protons (atomic number, \(Z\))…
