2. Metals have an important role in our daily life.
The discovery of metal is said to be the most
important milestone in the history of human
civilization. We cannot live without machines now.
All machines are made up of metals. Machines
reduce the work of man. Many modern facilities
would not have been possible without metals. Most
metals occur as their compounds in nature.

3. Some of the important metals that we use in our daily
life .....
