Choorine and sodium.

Answer:

Explanation:
Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).
Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>
The answer is since one electron carries a charge of
, the number
of electrons that make up -73pC
are


Thus, the housefly lost about 456 million electrons to the surface!
