Question

thanks @Lizo​

Answer 1

Answer:

A pure substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it. To help identify a metal, you could determine its density and compare it to the density of other metals.
