Metallic material -- iron ,still, gold, etc ....
Non-Metallic material-- precious stones, carbon , etc , we used daily.
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.
