What is the ratio of the neutrons present in Nitrogen and sulphur atoms with respect to their atomic mass of 14 and 32

Options

A. 7:16
B. 16:7
C. 14:32
D. 32:14

Explanation

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

### Step 1: Identify the atomic mass and atomic number
- The atomic mass of nitrogen (N) is 14.
- The atomic mass of sulfur (S) is 32.
- The atomic number of nitrogen (N) is 7.
- The atomic number of sulfur (S) is 16.

### Step 2: Calculate the number of neutrons in nitrogen
The number of neutrons can be calculated using the formula:
\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} \]

For nitrogen:
\[ \text{Number of Neutrons in Nitrogen} = 14 - 7 = 7 \]

### Step 3: Calculate the number of neutrons in sulfur
Using the same formula for sulfur:
\[ \text{Number of Neutrons in Sulfur} = 32 - 16 = 16 \]

### Step 4: Write the ratio of neutrons in nitrogen to neutrons in sulfur
Now we can express the ratio of the number of neutrons in nitrogen to the number of neutrons in sulfur:
\[ \text{Ratio} = \frac{\text{Number of Neutrons in Nitrogen}}{\text{Number of Neutrons in Sulfur}} = \frac{7}{16} \]

### Step 5: Simplify the ratio
The ratio of neutrons in nitrogen to neutrons in sulfur can be expressed as:
\[ 7:16 \]

### Final Answer
The ratio of the number of neutrons present in nitrogen and sulfur atoms is **7:16**.
