When silicon is doped with arensic, each arensic atom will give the crystal_____.

1. Two holes

2. One electron

3. Two electrons

4. One hole

Answer:- 2. One electron

When Arsenic is doped to Silicon, this forms four covalent bonds with the four valence electrons of Silicon. This results in the electron that is the fifth valence electron of Arsenic. Consequently, for every atom of Arsenic added to Silicon, one extra electron is produced.
