Question
Identify the least stable isotopes from all synthesized isotopes shown the below:
- 4H
- 5H
- 6H
- 7H
Hint:
It is formed by bombarding tritium with a fast moving tritium nuclei.
The correct answer is: 5H
The correct option is b)5H.
- 5H (atomic weight 5.03531) is a highly unstable isotope of hydrogen. Atomic nuclei consist of one proton and four neutrons.
- It was synthesized in the laboratory by bombarding tritium with fast-moving tritium nuclei.
- In this experiment, a tritium nucleus captures two neutrons from another neutron, resulting in a nucleus with one proton and four neutrons.
