If the atomic weight of C and Si are `12` and `28` respectively , then what is the ratio of the number of neutrons in them?

Options

A. `1:2`
B. `2:3`
C. `3:4`
D. `3:7`

Explanation

To find the ratio of the number of neutrons in carbon (C) and silicon (Si), we can follow these steps:

### Step 1: Identify the atomic weights and atomic numbers
- The atomic weight of carbon (C) is given as 12.
- The atomic weight of silicon (Si) is given as 28.
- The atomic number of carbon (C) is 6.
- The atomic number of silicon (Si) is 14.
