Question
Identify the radioactive isotope from the following?
- Boron -10
- Hydrogen -2
- Carbon -12
- Hydrogen - 3
Hint:
It is also called tritium.
The correct answer is: Hydrogen - 3
The correct option is d)Hydrogen - 3.
- It consists of two neutrons and one proton in its nucleus.
- Due to the synergistic effect of cosmic rays and atmospheric gases, trace amounts of hydrogen 3 or tritium are generated in nature.
- It is also released in small amounts during nuclear testing.
- It is radioactive and beta decays to helium-3.
- The atomic mass of hydrogen 3 is 3.0160492 u. Emits low-energy beta particles.

Read the following paragraph carefully.
X is prepared when the wood is heated in a limited air supply. This X is used to increase the absorption capacity of gases by heating them at a very high temperature. The substance obtained by this process is called Y. When this X reacts with the oxide of the metal, it gives the mixture of Z and W. This mixture is also called producer gas.
Identify the compounds X, Y, and Z in the above paragraph.
