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.

How many ions does MgBr2 have?
One formula unit of MgBr2 has three ions; one Mg2+ ion and two Br- ions. One mole of MgBr2 formula units has one mole of Mg2+ ions and two moles of Br- ions, for a total of three moles of ions.
What is the ionic formula for tin II bromide?
The ions are Sn2+ and Br-, so the formula is SnBr2.
What is the ratio of Sr2 plus ions to Br- ions in a neutral compound?
The atomic ratio Sr/Br is 2.
In and Br formula?
Br is the chemical symbol (not formula) of bromine.
What is the name of compound with the formula B2Br2?
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-
