Question

The elements, Si, Ga, As, Ge, Al, Cd, S and Se are all used in the manufacture of various semiconductor devices. Write the expected electron configuration for these atoms. Please helppp

Answer 1

Al (Group 13, Row 3) Al = [Ne] 3s^2 3p

Si (Group 14, Row 3) Si = [Ne] 3s^2 3p^2

S(Group 16, Row 3) S = [Ne] 3s^2 3p^4

Ga (Group 13, Row 4) Ga = [Ar] 4s^2 3d^10 4p

Ge (Group 14, Row 4) Ge = [Ar] 4s^2 3d^10 4p^2

As (Group 15, Row 4) As = [Ar] 4s^2 3d^10 4p^3

Se (Group 16, Row 4) Se = [Ar] 4s^2 3d^10 4p^4

Cd (Group 10, Row 5) Cd = [Kr] 5s^2 4d^10
