What is the half life period of tritium ?

Options

A. 13.33 year
B. 12.33 year
C. 12 years
D. 22.33 years

Answer

To find the half-life period of tritium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Half-Life**:
- The half-life of a radioactive substance is the time required for half of the radioactive atoms in a sample to decay.

2. **Identifying Tritium**:
- Tritium is a radioactive isotope of hydrogen, denoted as \( ^3H \).

3. **Researching Tritium's Half-Life**:
- The half-life of tritium is a well-documented value in nuclear chemistry.

4. **Stating the Half-Life**:
- The half-life period of tritium is approximately **12.5 years**.

5. **Interpreting the Meaning**:
- This means that after 12.5 years, half of the original amount of tritium will have decayed into other elements.

### Final Answer:
The half-life period of tritium is **12.5 years**.
