Do the Na^+, K^+ and NH4^+ share a particular property that makes their salts soluble?

Most of their salts are soluble because:
- they have only weakly polarising singly-charged positive ions so they form salts with low lattice energies
- they are larger than more highly-charged cations so they are highly solvated in aqueous solution and therefore have high hydration energies
The balance between low lattice energy and high hydration energy means they are likely to be soluble. Salts with very large anions (which have low hydration energies) may not be soluble.

sodium and potassium will form ionic salts that are polar. and since like dissolve like substances. since water is polar and the salts produce are polar ..then it will dissolve . hence soluble

Who said that ??? There are salts of these cations which are insoluble. For Sodium, the Uranate is insoluble and is used in the detection test.
