OCCURRENCE OF METALS

1.Iron was used in the earliest times of which we have any historical records. 2.The art of making weapons from iron was known to the Egyptians and Hindoos.3.The metal is widely distributed in nature in the form of silicates, oxides, and the sulphide,. 4.The chief ores of the metal are hematite, limonite,., magnetite, and siderite,.5. Iron occurs in plants and animals as a constituent of complex organic compounds.6. It is present in the hemoglobin of the blood and is involved in this condition in the absorption of oxygen in the lungs;7. The naturally occurring materials containing compounds of the metals which may be economically extracted are called ores. 8.The definite chemical compound of the metal in the ore is termed a mineral. 9.The name gangue is applied to the constituents of the ore other than the mineral containing the metal to be extracted.10.Iron is obtained by reducing its ores with carbon.

PROPERTIES OF METALS

1. The metals resemble one another in their general chemical behaviour with other substances, but they differ markedly in activity.2. The uses to which metals are put are based upon their physical or chemical properties.

3. The metals vary greatly in density. 4. The lightest is lithium, which has the density of 0.534 and is, therefore, about one-half as heavy as water.5.The heaviest is osmium (D. 22.48) which is closely related to platinum (D. 21.45) in physical and chemical properties. 6.The so-called light metals, of which sodium, potassium, magnesium and aluminium are examples, have a density less than 4;7. Iron, lead, tin, silver, etc. are known as heavy metals.

8.The metals also vary in hardness, from potassium, which can be molded like wax, to chromium, which will cut glass. 9.The metals and other substances differ in the extent to which they can resist a strain that tends to bring about a permanent change in their form.

1. The metals also vary in hardness, from potassium, which can be molded like wax, to chromium, which will cut glass. 2. The metals and other substances differ in the extent to which they can resist a strain that tends to bring about a permanent change in their form. 3. All substances offer more or less resistance to the flow of an electric current through them. 4. With any given substance, the resistance is determined by its dimensions and the temperature.5..The solids obtained when two or more metals are mixed in the molten condition and allowed to solidify are called alloys. 6. Each constituent of an alloy is called a component. 7.Alloys may be binary (two-component), ternary (three-component), etc. 8..The ability of various metals to form alloys differs greatly.
