Br⁻ ion has a lower ratio of charge to volume.
The charge density of an ion is defined as the ratio of the charge on an ion to its volume. The charge density of potassium ion is higher than bromide ion. The charge density of an ion is defined as the ratio of the charge on an ion to its volume.
The properties of an ion that affects its charge density are the magnitude of charge and volume of ion. Volume is governed by size. The more is the size of the ion, the more will be its volume. It is directly proportional to the magnitude of charge and inversely proportional to the volume of the ion.
Potassium and bromine atoms belong to the IV period with atomic numbers 19 and 35 respectively. Both atoms have a univalent charge with opposite charges. However, bromine has a relatively higher volume compared to potassium ion because the bromine atom has more number orbital compared to potassium and thus volume also will be small in potassium ion. Hence, the charge density of the potassium ion is higher than the bromide ion.
