Generally speaking, the higher the ionization energy a metal has the more soluble its salt will be.  However, the rules of solubility for ionic compounds are best explored through charts similar to the one below.  Once a suitable anion is found that will allow for solubility in aqueous solution, the higher the coresponding alkali metal is in the Periodic Table the more soluble it will be: beryllium chloride is more soluble than barium chloride.
