An ionic formula, like \(\ce{NaCl}\), is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Sodium sulfide, another ionic compound, has the formula \(\ce{Na ...Small cation: the high polarizing power stems from the greater concentration of positive charge on a small area. This explains why LiBr is more covalent than KBr (Li + 90 pm cf. K + 152 pm). Large anion: the high polarizability stems from the larger size where the outer electrons are more loosely held and can be more easily distorted by the cation.Extending the study to multi-valent ions, inorganic polyatomic ions, and even larger organic ions would further shed light on these complex and intriguing interactions. References Nitopi, S. et al ...The formula for an ionic compound follows several conventions. First, the cation is written before the anion.
