Question 2 • SVHS Chemistry 1 $FA

Which shows the electron configuration for Silicon (Si)?

Answer
A
[Ar]4s23d104p4
B
[Ar]3d14s2
C
[Ne]3s23p4
D
[Ne]3s23p2

Explanation

Silicon has 14 electrons. The [Ne] core accounts for 10 electrons, and the remaining 4 fill the 3s orbital with 2 electrons and the 3p orbital with 2 electrons, giving [Ne]3s²3p². Therefore, choice D, [Ne]3s²3p², is correct.
