impurity is nothing but a foreign element. donor corresponds to donating an e-. So donor impurities are those which generally have 1 e- more than the material ( generally semiconductors) in which they are doped so that after covalent bonding they can donate that extra e-.

Difference between donor and acceptor impurities in semiconductors?
donor--arsenic, phosphorus, nitrogen acceptor--boron, aluminum, gallium
What is extrinsic conductor?
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
Acceptor atom create in semiconductor crystals?
If an acceptor atom is placed in a pure semiconductor, it will accept one or more electrons from the valence band of the semiconductor. This will permit positive holes in the conduction band to carry electrical current - the overall result is that the material will behave as a p-type semiconductor.
Examples of commonly used P-Type and N-Type in purities?
Examples of P-Type Impurities are Boron,Indium and Gallium arsenide Examples of N-Type Impurities are Antimony,Phosphurus
Characteristics of good acceptor circuit?
It needs to be in good working order. If there are any cracks or tears in it, then it might not work properly.
