Question

explain where and why metallic material and non metallic material has been used in your home​

Answer 1

Answer:

For most people, metal is another word for iron, steel, or a similar hard, shiny substance.

But does this definition fit with the true properties of metals

Before we explain, you should know that most of the elements in the periodic table are metals.

Metals are found in the center and left side of the periodic table. They can be further classified as alkali metals, alkaline earth metals, transition metals, and basic metals.

Properties of Metals

An element is a substance made up of one kind of atom; it cannot be separated into simpler parts. For example, the element helium (think hot-air balloons) is made up exclusively of helium atoms.

Elements are generally classified as metals or nonmetals (although some elements have characteristics of both; these are called metalloids).

Three properties of metals are:

Luster: Metals are shiny when cut, scratched, or polished.

Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped. For centuries, smiths have been able to shape metal objects by heating metal and pounding it with a hammer. If they tried this with nonmetals, the material would shatter! Most metals are also ductile, which means they can be drawn out to make wire.

Conductivity: Metals are excellent conductors of electricity and heat. Because they are also ductile, they are ideal for electrical wiring. (You can test this using some household items.

Answer 2

Answer:

This view of materials for engineering and structural applications looks at metals, plastics, other non-metals such as concrete and timber, and finally composites, and evaluates likely developments in the light of the current situation and visible trends. Unless demand for all materials comes to exceed supply it is likely that there will be intense rivalry between metals and non-metallic materials in which discovering and employing cheaper methods of production will play a decisive part.
