Question:
Which of the following is a stable nucleus?
Which of the following is a stable nucleus?
Show Hint
Stable nuclei usually have an even number of protons and neutrons, as this configuration minimizes the nuclear forces and leads to stability.
Updated On: Apr 10, 2025
- The nucleus with even protons and odd electrons
- The nucleus with even number of protons and neutrons
- The nucleus with even neutrons and odd protons
- The nucleus with odd protons and neutrons
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Nuclear Stability
In nuclear physics, a stable nucleus generally has an even number of protons and neutrons.
This configuration leads to a more stable nuclear structure due to paired interactions between protons and neutrons.
Step 2: Explanation of Other Options
Option (a) is incorrect because the number of electrons does not affect the stability of the nucleus, and a nucleus cannot have an odd number of electrons while being neutral.
Option (c) is incorrect because a nucleus with an even number of neutrons and odd protons is typically unstable.
Option (d) is incorrect because a nucleus with both odd protons and neutrons is also usually unstable.
Step 3: Conclusion Thus, a stable nucleus typically has an even number of protons and neutrons.
