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?\nan 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.\nan 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.\nan 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.\nan 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

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.

Explanation:

Step1: Analyze valence - electrons

Silicon has 4 valence electrons, arsenic has 5 valence electrons.

Step2: Consider doping effect

In n - type doping (arsenic in silicon), extra electrons are added.

Step3: Determine conductivity change

The extra electron from arsenic can be easily donated (lost), increasing conductivity.
