In chemical nomenclature, "Br" represents the prefix "bromo-," which indicates the presence of a bromine atom in a compound. Bromine is a halogen element with the atomic number 35. When naming organic compounds, the prefix "bromo-" is used to denote the substitution of a hydrogen atom with a bromine atom in the molecule.
Both of does prefixes mean not. In this case, these prefixes make words the opposite of what they mean.

Dis means away
Does prefixes mean to or toward. One common word with this prefix is about.
Theses prefixes, such as ig, il, im, in and ir, mean "not". Examples: ignoble - not noble illegal - not legal imperfect - not perfect inconsistent - not consistent irregular - not regular
No, formulas of ionically bonded compounds can be figured out without prefixes and understanding of how many electrons are gained/lost. In covalent bonds, prefixes are needed and without them the formulas and quantities couldn't be determined.
This is a method to distinguish different compounds.
Prefixes are used.
Ions combine in only one ratio. -APEX
two ions can combine in only one combination
two ions can combine in only one combination
The same atoms can combine in more than one ratio.
Prefixes are not used in naming ionic compounds because the charges of the ions involved determine the ratio in which they combine, thus eliminating the need for numerical prefixes to specify the number of atoms of each element. Ionic compounds are named using the names of the individual ions involved, without using prefixes to indicate the number of atoms.
