Question

State five use of metal and five use of non-metal.

Answer 1

Hint :Metals are elements that readily form positive ions (cations) and have metallic bonds in chemistry. Metals are often represented as a cloud of delocalized electrons surrounded by a lattice of positive ions. Metals' bulk properties are the subject of the conventional description.

Complete Step By Step Answer:
Metals: A metal is any chemical element that is an efficient conductor of electricity and heat. With non-metals, a metal may also form bonds and cations. To form positive ions or cations, atoms inside a metal easily lose electrons.
Uses of metals:
1. Jewellery and ornaments are made of gold, platinum, and silver.
2. Construction materials include iron and steel.
3. Utensils made of aluminium and steel are used.
4. In thermometers, mercury is used to verify the temperature.
5. Insulation wires are made of aluminium.
Non-Metals: Non-metals are elements on the periodic table's right side. Gases, liquids, and solids are all examples of non-metals. Non-metals are not as polished as metals and have a dark colour. You can't hammer or form a non-metal; if you strike it, it will break. Non-metal sulphur is an example. It's yellow, and if you strike it with a hammer, it breaks. Non-metals are insulators, which means they don't conduct electricity well.
Uses of Non-Metals:
1. Breathing requires oxygen.
2. Chlorine is a chemical that is used to purify water.
3. Crackers contain phosphorus.
4. Fertilizers include non-metals such as nitrogen.
5. Fertilizers contain potassium.

Note :
Graphite is not a metal, but the delocalized (free) electrons in its structure enable it to conduct electricity. This is due to the fact that each carbon atom in graphite is only bound to three other carbon atoms and has a free fourth valence electron.
