There is only one resonance structure for BCl3. Boron is attached by three single bonds to the three Chloride atoms and there are three lone pair electrons around the chlorine atoms. There are no resonance structures because they are all single bonds.

There are three possible, equally distributed, resonance structures of nitrate (NO3-).Cf. Related links for the possible Lewis structure of them, on the lowest half of that page.
There are two resonance structures for bromate - two of the oxygens are double bonded to bromine, and one is single bonded. The double bonded bromines share the electrons between all three, creating two equivalent resonance structures.
There are 18 electrons in a chloride ion.
