Germanium, Ge (number 32 ), computer chips operate faster than silicon, Si (number 14), computer chips. So how might a gallium, Ga (number 31 ), chip compare with a germanium chip?
A) A gallium chip would be even faster because the gallium is more metallic.
B) A gallium chip would be slower because its electrons are more loosely held.
C) Gallium is located just below aluminum, which is widely known to be an electrical insulator.
D) Gallium is more nonmetallic and so it does not conduct electrons very well.
