ChemicalTo determine it, you must alter the identity of the substance. See the Related Questions link to the left of this answer: "What is the difference between a chemical and physical property?"PhysicalElements cannot be altered, without disrupting the physical structure of the atom, so the atomic structure between the protons, neutrons, and electrons are physical.Barney9So which one is it...? Chemical or physical?~Physical. Barney9's answer was a little confusing.. but overall, you can identify an element without disrupting the atomic structure of it's atoms.
