Salt is the solute, water is the solvent
Elements with the same properties would be in the same group (Up and down row). Look at a periodic table and see which of the elements are in the same group. That will be your answer.<span />
With various extractions the amount of material left in the trash will be lower, ergo the extraction will be more perfect. Various extractions with fewer amounts of solvent are more efficient than a single extraction with a huge amount of solvent.

Surely multiple extractions are better than the single large extraction. Because extraction is about maximizing outside field communication between the two solvents, and you easily get more surface area contact with fewer amounts.
You can merge two smaller portions quicker and more completely than with large portions.
