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?\no an atom of arsenic has one fewer valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom gains an electron.\no an atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom loses the electron.\no an atom of arsenic has one fewer valence electron and fewer electron shells than an atom of silicon, so the conductivity increases because the arsenic atom gains an electron.\no 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.

Answer

Brief Explanations:

Silicon has 4 valence electrons. Arsenic is in Group 15 and has 5 valence electrons. In doping, the extra valence - electron from arsenic can be easily donated (lost) to the conduction band, increasing the number of charge - carriers in silicon and thus increasing its conductivity. Also, arsenic has more electron shells than silicon.

Answer:

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.
