A triton contains (neutron /proton)

Options

A. `8:1`
B. `6:1`
C. `4:1`
D. `2:1`

Explanation

To determine the ratio of neutrons to protons in a triton, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Isotope**: Triton is the nucleus of the isotope Tritium, which is represented as \( ^3_1H \). This indicates that Tritium has a mass number of 3 and an atomic number of 1.

2. **Understand Atomic Number and Mass Number**:
- The atomic number (1) tells us the number of protons in the nucleus. Therefore, Tritium has **1 proton**.
- The mass number (3) represents the total number of protons and neutrons in the nucleus.

3. **Calculate the Number of Neutrons**:
- The number of neutrons can be calculated using the formula:
\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Number of Protons} \]
- Substituting the values:
\[ \text{Number of Neutrons} = 3 - 1 = 2 \]
- Thus, Tritium has **2 neutrons**.

4. **Determine the Neutron to Proton Ratio**:
- The ratio of neutrons to protons is given by:
\[ \text{Neutron to Proton Ratio} = \frac{\text{Number of Neutrons}}{\text{Number of Protons}} = \frac{2}{1} \]
- Therefore, the neutron to proton ratio in Triton is **2:1**.

### Final Answer:
The triton contains a neutron to proton ratio of **2:1**.
