KBr2 does NOT exist, bromide (being Br-) has a valency of (minus) one, so the only possibility is KBr, potassium bromide, in solution as ions: K+ and Br-
K and Br are most likely to form a chemical compound.
write down the formulae of the ionic compounds which contain the following pairs of a) Ca2+ and P3---->Ca3P2 b)Fe3+ and Br---->FeBr3 c) Mg2+ AND NO-3---> Mg3NO2 D) NH4+ AND S2----> S2(NH4)
The chemical formula K3PO4 is for tripotassium phosphate.

If there were a chain of 20K and Br atoms attached to each other, somehow, then the formula would be written as K20Br20. Since only one K+ ion attaches to one Br- ion, the formula is written as KBr, regardless of how many are there.

Potassium bromide... K+ + Br- --> KBr
The cation,K +and the anion,Br -form the ionic compound,KBr==============Potassium bromide
K is Potassium and Br is Bromine. These are both Elements but together they form a compound
