Calculate the electonegativity of silicon using Allred -Rochow method .(Covalent radius of silicoan `=1.175Å)`.

Explanation

To calculate the electronegativity of silicon using the Allred-Rochow method, we will follow these steps:

### Step 1: Write the Electronic Configuration of Silicon
Silicon has an atomic number of 14. Its electronic configuration can be written as:
\[ \text{Si: } 1s^2 \, 2s^2 \, 2p^6 \, 3s^2 \, 3p^2 \]

### Step 2: Calculate the Effective Nuclear Charge (Z_eff)
The effective nuclear charge (Z_eff) can be calculated using Slater's rules. The formula for Z_eff is:
