Question

Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. How does the addition of arsenic change the conductivity of silicon?

Answer 1

Answer:

Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. ... An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron
