It partly depends on how much you have. For example, it would be easy to tell the difference between silver and gold if you had enough of each. Similarly you could easily tell the difference between tin and hydrogen. But if you onlyhad a few atoms of each it would not be easy. You could try to combine the elements with another element and dissolve the residual companound in water and do a chromatograhy test on each one.

Gold is a malleable element. Silver is another malleable element.
An element or ion moves out of one compound and into another. (One element is replaced by another in a compound.)
One element decaying into another, which decays into another
The number of their neutrons.
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.

Yes it is an element with 12 protons.A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, the number of protons in its nucleus.
It is a solution.
An element can be distinguished by only one atom of an element because it has significant properties, while a molecule has to be found by two atoms like O2 and H2.
An element's atomic number, or number of protons, differentiates one element from another.
