Full Answer
What describes a chemical property of aluminum?
Aluminum is a soft and lightweight metal. It has a dull silvery appearance, because of a thin layer of oxidation that forms quickly when it is exposed to air. Aluminum is nontoxic (as the metal) nonmagnetic and non-sparking. Aluminum has only one naturally occurring isotope, aluminium-27, which is not radioactive.
