What is the ratio of the neutrons present in Nitrogen and Carbon atoms with respect to their atomic mass of 14 and 12

Options

A. 7:6
B. 6:7
C. 14:12
D. 12:14

Explanation

To find the ratio of the neutrons present in nitrogen and carbon atoms with respect to their atomic masses, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Mass and Atomic Number:**
- For Nitrogen (N):
- Atomic Mass = 14
- Atomic Number = 7
- For Carbon (C):
- Atomic Mass = 12
- Atomic Number = 6

2. **Calculate the Number of Neutrons:**
- The number of neutrons in an atom can be calculated using the formula:
\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} \]
- For Nitrogen:
\[ \text{Neutrons in Nitrogen} = 14 - 7 = 7 \]
- For Carbon:
\[ \text{Neutrons in Carbon} = 12 - 6 = 6 \]

3. **Set Up the Ratio:**
- The ratio of neutrons in Nitrogen to the neutrons in Carbon is:
\[ \text{Ratio} = \frac{\text{Neutrons in Nitrogen}}{\text{Neutrons in Carbon}} = \frac{7}{6} \]

4. **Express the Ratio:**
- The ratio of the neutrons present in Nitrogen and Carbon is:
\[ 7 : 6 \]

### Final Answer:
The ratio of the neutrons present in Nitrogen and Carbon atoms is **7:6**.
