Elements used in computer chips have both metals and non metals. they are located in which region of the periodic table

I'm not sure how to answer this question...
If you look at this picture of the periodic table, the greens are metals, the nonmetals are orange, and the metalloids are blue. Hope it helps!

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
