Addition of pentavalent impurities to Si will result in each dopant forming bonds with 4 si atoms and, so 1 atom of the dopant will be left out.
On adding a trivalent impurity, the dopant will form a bonds with 3 Si atoms...so how does an electron disappear to make a hole?
Why does the dopant form only a single bond with silicon?...why not triple? Chemical properties I presume?
