Question

Mention the importance of metals to man

Answer 1

Answer:

Metals are solid substances obtained from the earth.

Metal uses are many and this is due to their natural properties of rigidity, ductility, tensile strength, etc.

They have high atomic weights and numbers in the periodic table.

Their oxides are alkaline in nature so they can resist acids.

Metals are very strong, durable and highly resistant to natural wear and tear.

Hence they have been used widely by man since ancient ages.

In the past, these metals were profoundly used for cooking, farming tools, weapons (bow, arrows, swords) and also in locomotive wagons.

But with growth in technology, the horizons of their use has widened enormously.
