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.
The sulfate ion has four resonance structures.
3
4
When two or more valid electron dot structures that have the same number of electrons pairs for a molecule or ion.
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.
The sulfate ion has four resonance structures.

Oxygen is transferred from bromate ion(s) to the Chromium ion. Leaving hypobromous ion, and/ or bromide ion.
When two or more valid electron dot structures that have the same number of electrons pairs for a molecule or ion.
