# Need clarification on solubility interaction

- Is this statement true? Cation tend to be smaller than anions because when an electron is removed from a neutral atom, the nucleus (+) would be held more tightly (contracts) . Anions tend to be bigger (add electron), and thus you have a extra negative charge on the outside, the extra electron want to be repelled by the other electrons thus charge of anion gets bigger. [Sorry bad grammar]
- Why can cations solvate more readily than anions
- When water dissolute NaCl, does that mean that the polar water molecules effectively isolates the sodium and chlorine ion thus becoming a solution?
- Is it true as sodium chloride dissolves, four water molecules attach to the sodium ion? then how many bond with chlorine

Thanks ALOT to the people who helped me!!!
