Question:
For a light nuclei, which of the following relation between the atomic number (Z) and mass number (A) is valid
For a light nuclei, which of the following relation between the atomic number (Z) and mass number (A) is valid
Show Hint
Light nuclei have nearly equal protons and neutrons.
Updated On: May 1, 2026
- $A = Z/2$
- $Z = A$
- $Z = A/2$
- $Z = A^2$
- $A = Z^2$
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
For light nuclei: \[ N \approx Z \Rightarrow A = Z + N \approx 2Z \]
Step 1: Relation.
\[ A \approx 2Z \Rightarrow Z \approx \frac{A}{2} \]
