WebMetals offer a wide variety of aesthetic qualities - some, like lead, are dull, and some can be polished to a mirror-like finish. Metals can be smooth after machining or textured after being cast. Metals come from an ore that is mined from the ground. A huge amount of heat energy is needed to extract the metal from the ore - this energy often ... WebThe reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.

Metal extraction and the reactivity series - BBC Bitesize
WebAluminium is more reactive than carbon so it must be extracted from its compounds using electrolysis. Even though aluminium is more abundant than iron in the Earth's crust, aluminium is more... WebThe ability of metals to conduct electricity stems from their delocalised electrons. As these are free to move, an electrical current can flow through metallic materials. The electrochemical... WebThe method used to extract metals depends on the reactivity of the metal. The reactivity series allows us to predict how metals will react.
