 * ======**10.1 Properties of metals**====== ||
 * ====== 1  ====== || ======Distinguish between metals and nonmetals by their general physical and chemical properties.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Identify and interpret diagrams that represent the structure of an alloy.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Explain why metals are often used in the form of alloys.====== ||   ||   ||   ||   ||
 * ======**10.2 Reactivity series**====== ||
 * ====== 1  ====== || ======Place in order of reactivity: potassium, sodium, calcium, magnesium, zinc, iron,======

• dilute hydrochloric acid (except for alkali metals).
||  ||   ||   ||   ||
 * ====== 2  ====== || ======Compare the reactivity series to the tendency of a metal to form its positive ion, illustrated by its reaction, if any, with:======

• the oxides of the other listed metals.
||  ||   ||   ||   ||
 * ====== 3  ====== || ======Deduce an order of reactivity from a given set of experimental results.====== ||   ||   ||   ||   ||
 * ======**10.3 Extraction of metals**====== ||
 * ====== 1  ====== || ======Describe the use of carbon in the extraction of some metals from their ores.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Describe the essential reactions in the extraction of iron in the blast furnace.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Relate the method of extraction of a metal from its ore to its position in the reactivity series.====== ||   ||   ||   ||   ||
 * ======**10.4 Uses of metals**====== ||
 * ====== 1  ====== || ======Explain the use of aluminium in aircraft manufacture in terms of the properties of the metal and alloys made from it.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Explain the use of zinc for galvanising steel, and for sacrificial protection.====== ||   ||   ||   ||   || ﻿ ||
 * ====== 3  ====== || ======Explain the use of aluminium in food containers because of its resistance to corrosion.====== ||   ||   ||   ||   ||
