Feb 15, 2013 · The core is a dense ball of the metals iron and nickel. After observing the speeds of P-waves and S- waves, scientists have concluded that the earth’s center is divided into two layers, the outer core and the inner core. The Outer Core. The outer core is so hot the iron and nickel metals …

Part One : Metals. Introduction. An activity series of metals is a list of metals arranged in order of decreasing chemical activity (i.e., from most to least reactive). To experimentally determine which of two metals is more reactive, prepare two solutions. First, place a piece of one metal in an aqueous solution of a compound of the other metal.

An alloy usually contains two or more metals and it usually appears homogeneous when viewed by eye. It may contain non-metals as solutes and may be either homogeneous or heterogeneous when viewed with a microscope. It rarely occurs that an alloy is a compound of more than 1 metal.
