If metal A displaces metal B from its solution, it is more reactive than B. Reaction of Metals with Salt Solutions: Reactive metals can displace any metal less reactive than itself, from the oxide, chloride or sulphate of the less reactive metal in solution or their molten state. Reaction of Metals with Acids: Metals are usually displace hydrogen from dilute acids (Except copper, silver and gold do not displace hydrogen from dilutes acid because they are less reactive than other metals). Reaction of Metals with Water: Metals react with water to form a metal hydroxide and Hydrogen gas. Reaction of Metals with Oxygen: When metal are burnt in air, they react with the oxygen to form metal oxide. The chemical metal chemical properties of metals are discussed below: The electropositive nature allows metals to form compounds with other elements easily. Sodium metal forms sodium ions Na+, Mg forms positively charged Magnesium ions Mg2+and aluminium forms aluminium ions Al3+. Metals are very reactive and tend to losses electrons easily and form positively charged ions therefore metals are called electropositive elements. They have high densities (except Sodium and Potassium).They have high melting and boiling points (except Sodium and potassium).They are solid at room temperature (Except Mercury).Aluminium, Iron, Calcium, Sodium, Potassium, and Magnesium are the major metals is found abundance in the earth’s crust (names are in decreasing order).These elements form positive ions by loosing electrons (or donating).They are good conductor of heat and electricity and are malleable and ductile.Also the elements which are located extremely left have most metallic properties. In the periodic table, these elements are located and confined towards left and middle. There are similarities as well as differences are the properties of these elements on the basis of their, all the element can be divided three types: Metal non- Metal metalloid Metals are those elements which losses electrons and provides cation.
