Question

In gamma ray emission form a nucleus (A) there is no change in the proton-number and neutron number (B) Both the number are changes (C) only Proton number change (D) only neutron number change

Short answer

\( \Rightarrow \) The correct answer is (A) There is no change in the proton-number and neutron number during gamma-ray emission from a nucleus.

Step-by-step solution

Understand Gamma-Ray Emission

Gamma-ray emission occurs when a nucleus in an excited state (i.e., with excess energy) transitions to a lower energy state by emitting a high-energy photon known as a gamma-ray. This process does not involve the change of any particles within the nucleus.

Analyze the Options

Now, let's analyze each option and determine which one is correct based on our understanding of gamma-ray emissions. (A) No change in the proton-number and neutron number. This statement aligns with our understanding that gamma-ray emission does not involve any changes in the composition of the nucleus. (B) Both proton and neutron numbers change. This statement contradicts our understanding of gamma-ray emissions as they do not involve changes in the composition of the nucleus. (C) Only Proton number change. This statement is also inconsistent with our understanding of gamma-ray emission, as it does not involve any changes in the composition of the nucleus. (D) Only neutron number change. This statement, like the others, contradicts our understanding of gamma-ray emission, as it does not involve any changes in the composition of the nucleus.

Choose the Correct Option

Based on our analysis and understanding of gamma-ray emissions, we can conclude that the correct answer is: (A) There is no change in the proton-number and neutron number during gamma-ray emission from a nucleus.
