Question

How can you know if a solution is electrolytes or non-electrolytes? if it is all metal??

Answer 1

Paul is right, if it conducts electricity it's electrolyte solution. All metal part, well NaCl - sodium chloride, that paul mentioned is not metal at all. So, all metals doesn't make sense.  

Answer 2

If you dissolve an electrolyte, such as sodium chloride, in water, you get a solution that conducts electricity.

If you dissolve a non-electrolyte, such as ordinary sugar, the solution doesn't conduct electricity because there are no charged particles.  (It may conduct just a little bit, because of impurities)

I don't understand what you mean by "all metal".
