Question

which model represents the electron dot diagram of silicon? si (with dots), .si. (with dots), .si. (with dots)

Explanation:

Step1: Find silicon's valence electrons

Silicon (Si) is in group 14, so valence electrons = 4.

Step2: Check electron dot diagrams

Electron dot diagrams show valence electrons around the symbol. Count dots in each option: Left has 4, Middle has 3, Right has 3.

Answer:

The Left Graph (Si with 4 dots)
