Aicharya · Accepted Answer

Pentavalent impurities are the atoms with five valence electrons used for the doping of semiconductors. i.e. Arsenic (As), Phosphorous (Pi), Antimony (Sb), etc. Arsenic is an example of pentavalent impurity. They have 5 valence electrons. For n-type semi-conductor intrinsic semiconductor is doped by pentavalent impurity.
