Question:
Identify unstable isotope of hydrogen from the following.
Identify unstable isotope of hydrogen from the following.
Show Hint
Recall which of the three hydrogen isotopes is radioactive.
Updated On: Nov 12, 2026
- Hydrogen
- Deuterium
- Tritium
- Deuterium and Tritium
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Hydrogen has three isotopes: protium, deuterium and tritium.
Step 2: Stability
Protium and deuterium are stable. Tritium is radioactive and emits low-energy \(\beta\) particles.
Step 3: Conclusion
So tritium is the unstable isotope.
Final Answer:
Tritium is the unstable isotope of hydrogen. \[ \boxed{\text{(C) }\text{Tritium}} \]
