Answer
Answer:
D. [Ne] 3s² 3p²
Explanation:
Step1: Determine atomic number of silicon
Silicon has atomic number ( Z = 14).
Step2: Find noble gas core
Neon ((Ne)) has atomic number ( Z = 10). So, we use ([Ne]) as the core.
Step3: Calculate remaining electrons
(14-10 = 4) electrons left.
Step4: Distribute remaining electrons
Electrons fill (3s) (holds 2 electrons) and then (3p) (next sub - shell). So, (3s^{2}3p^{2}).
So the noble gas configuration for silicon is ([Ne]3s^{2}3p^{2}), which is option D.
