Question

What are particles of `LiCl` (ionic compound) called?

Answer 1

Ions?

Explanation:

Of course `LiCl` is a non-molecular material consisting of an infinite array of close packed `Li^+` ions, interpenetrated by an infinite array of close packed `Cl^-` ions (or vice versa). We can't speak of lithium chloride molecules, but we can speak of lithium chloride formula units, and we certainly can speak of `Li^+` and `Cl^-` ions. Capisce?
