We know that K (Potassium) forms a 1+ ion. We also know that Br (Bromine) forms a 1- ion. therefore D. KBr is correct
the right answer is D) KBr because potassium has vallence 1 and the same too with brom and vallence one it's not written
The correct formula for potassium bromide is K B r because potassium forms a +1 charge and bromine forms a -1 charge, which balance each other out in a 1:1 ratio. Options A, B, and C incorrectly suggest combinations that do not balance the charges of the ions. Therefore, the correct answer is D: K B r .
