PROPERTIES OF METALS.
The metals resemble one another in general chemical behaviour with other substances, but they differ markedly in activity.
The uses to which metals are put are based upon their physical or chemical properties. The metals vary greatly in density. The lightest is lithium, which has the density of 0.534 and is, therefore, about one-half as heavy as water. The heaviest is osmium (D. 22.48) which is closely related to platinum (D. 21.45) in physical and chemical properties. The so-called light metals, of which sodium, potassium, magnesium and aluminum are examples, have a density less that 4; iron, lead, tin, silver, etc. are known as heavy metals.
The metals also vary in hardness, from potassium, which can be molded like wax, to chromium, which will cut glass. 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. All substances offer more or less resistance to the flow of an electric current through them. With any given substance, the resistance is determined by its dimensions and the temperature.
The solids obtained when two or more metals are mixed in the molten condition and allowed to solidify are called alloys. Each constituent of an alloy is called a component. Alloys may be binary (two-component), ternary (three-component), etc. The ability of various metals to form alloys differs greatly.
