Lithium and cesium are both highly reactive metals that will react violently with water (forming a hydroxide compound and giving off hydrogen gas) so the question of relative solubility doesn't really arise.
Yes, Cesium cyanide is soluble as are all cesium compounds.
No, it is an insoluble compound.
Lithium Sulfate (Li2SO4) is, indeed, SOLUBLE because the anion (SO4 2-) is soluble in an aqueous solution. Likewise, the Lithium cation (Li +) is soluble because it is located in the 1A family (or group), which consists of the Alkali Earth Metals, which are all soluble in an aqueous solution. Therefore, Lithium Sulfate is SOLUBLE.
If CsAt would be prepared, would behave as a polar molecule and soluble in water.
Yes, three salts of group 1 elements (Lithium, Sodium Potassium and salts) are soluble in water.
Yes, Cesium cyanide is soluble as are all cesium compounds.
Cs3PO4 is soluble in water. As are all cesium (Cs) compounds.
Yes, a lithium ion is soluble in a number of things. It is certainly soluble in water.
No, it is an insoluble compound.
Cesium is more reactive. Down the group reactivity increases.
You are misinformed, Lithium Chloride IS soluble in water.

yes it is soluble "soluble" is not a scientific term. But most agree that a solubility of .001 molar is not really soluble. If you look for the actual solubility, you will find by that definition, LiF is not soluble in water. (or at the least, slightly soluble in water.) Anyone who says LiF is soluble n water has never done an experiment in the lab to see that lithium fluoride precipitates very nicely out of water when formed.
Yes, three salts of group 1 elements (Lithium, Sodium Potassium and salts) are soluble in water.
Lithium hydroxide is soluble in water.
The hydroxide of Lithium is most soluble but all the hydroxides of alkali metals are completely soluble in water.
