Knowledge Fact :-

• The earth's crust is the biggest source of metals. Some soluble salts of the metals are also found in sea-water.

• Metals occur in nature sometimes free but mostly in combined state. The natural mode of occurrence of a metal is largely dependent on its chemical nature. Those metals which are least reactive and have little or no affinity for oxygen, moisture and other chemical reagents occur in free or metallic or native state,

i.e., in uncombined state.

• Most of the metals are reactive and hence are found in combined state, i.e., as compounds.

• The natural substances in which the metals or their compounds occur in the earth are called minerals.

• The mineral has a definite composition. It may be a single compound or a complex mixture. The minerals from which the metals can be conveniently and economically extracted are known as ores. All the ores are minerals but all minerals cannot be ores.
