Question

What are metals and nonmetals and give their example?

Answer 1

Metals are hard, shiny, ductile, malleable, are good conductors of heat and electricity, and are solid at room temperature. eg- Gold, Silver, Iron.

Non-metals are dull in appearance, brittle, bad conductors of heat and electricity, can be solid, liquid or gas. Ex- Chlorine, argon, oxygen.

Basically, elements are classified into metals and non-metals according to their physical and chemical properties.The chemical elements in pure form are classified as metals. They usually have 1-3 electrons in their outer shell.and they can easily lose their valence electrons.They are the good conductors of heat and electricity.Some of the physical properties of metals include ductile and malleable properties.They are generally solid at room temperature.Some of the examples of metals are calcium, magnesium, sodium, aluminum, zinc etc.

Nonmetals usually have 4-8 electrons in their outer shell and they can easily gain and share the valence electrons. They are poor conductors of heat and electricity. and don't possess metallic luster..They are generally solid, liquid, or gas at room temperature.Some of the examples of nonmetals are carbon, oxygen, nitrogen, phosphorus etc.
