what is similar to potassium chloride
Sodium chloride and potassium chloride are ionic compounds. Both are solids, where cations and anions are in a closed packed structure. Sodium and potassium are group 1 metals, which have the capability to make +1 cations.Chloride is the -1 anion made by group 7 element, chlorine.Since group 1 elements are electropositive and group seven elements are electronegative, their electronegativity difference is larger. So they form ionic bonds.odium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine.
