Question

introduction of metal and non metal in 200 words

​

Answer 1

Answer:

Metals and Nonmetals are different types of materials present around us. Metals (like copper and aluminium) are good conductors of heat and electricity, while nonmetals (such as phosphorus and sulfur) are insulators. ...

Answer 2

Metals

Metals are materials holding or possessing the characteristics of being shiny, hard, fusible, malleable, ductile, etc. Few examples of metals (materials) are – Gold, Silver, Aluminium, Copper, Iron, etc.

Properties of Metal

• They are Lusture.
• They are Malleable.
• They are Ductile.
• They are good conductor of heat and electricity.
• They are Sonorous.
• They are solid accept Mercury.

Uses of Metals

Metals are used for various purposes, from making wires and sheets. For example – Copper and aluminum wires in electrical equipment’s, especially for conduction of electricity.

Metals are also used in making automobiles, machinery, water boilers, industrial gadgets, etc.

The metals are used in making utensils and water boilers due to its property of being a good conductor of heat.

Non-Metals

Non – metals are materials not holding the characteristics of metals, means they are not shiny, hard, fusible, malleable, ductile, etc. Many materials like coal and Sulphur are very soft and dull in appearance. They break down into very fine thin powdery mass on tapping with the hammer. They are neither in – sonorous and also are a very poor conductor of heat and electricity. Few examples of non – metals are carbon, oxygen, Sulphur, etc.

Properties of Non-Metal.

• The solid non-metals are brittle or dull and soft as they can be broken down into a powdery substance or mass on tapping down with the hammer. Few examples are Coal and Sulphur. However, Diamond is an exception as it is the hardest non-metal.
• Non – metals may be either solids, liquids, or gases.
• Non-metals are poor conductors of heat and electricity except Graphite.
• They do not possess metallic luster.
• Non-metals are not sonorous, they do not produce a ringing sound.
• Non-metals possess no malleability.
• They are not ductile.
• They have dull luster, however, iodine is lustrous.

Some example of non – metals are carbon, oxygen, Sulphur, phosphorous, and many more.

Uses of Non-Metal.

Many non-metals like chlorine, Sulphur, iodine are very useful for medicinal purposes.

Non-metal like oxygen is very essential for our life for respiration.

We use nitrogen phosphorus in fertilizers for better plant growth and enhance the fertility of the soil.

Non-metal like Sulphur is useful in crackers.

Chlorine and Fluorine are useful for the water purification purpose.
