differences between metals and non metals
Answers
Answer:
non-metals may be solid, liquid and gaseous at room temperature. Metals are good conductors of heat and electricity but non-metals are poor conductors of heat and electricity. Metals are ductile in nature i.e. it can be drawn into thin wires.
Explanation:
Difference Between Metals and Non-metals
metals vs non metalsIdentification of metals and non-metals is a bit difficult if you do not have any idea of their characteristics. While a metal is a solid substance, usually hard, lustrous and opaque. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
The matter is a physical substance that occupies space and has mass. It is present in three forms, which are elements, compound and mixture. Out of these three forms, elements is the purest form of matter and grouped into three categories, i.e. metals, metalloids and non-metals. Based on the physical and chemical properties, these three elements are bifurcated.

BASIS FOR COMPARISON METALS NON-METALS
Meaning Metals refers to the natural elements that are hard, shiny, opaque and dense. Non-metals implies those chemical substances that are soft, non-shiny, transparent and brittle.
Example metal non-metal
Nature Electropositive Electronegative
Structure Crystalline Amorphic
Physical State at room temperature Solid (except mercury and gallium) Solid or gas (except Bromine)
Density High density Low density
Appearance Lustrous Non-lustrous
Hardness Most metals are hard, except sodium. Most non-metals are soft, except diamond.
Malleability Malleable Non-malleable
Ductility Ductile Non-ductile
Sonorous Sonorous Non-sonorous
Conduction Good conductor of heat and electricity Poor conductor of heat and electricity
Melting and Boiling point Very high melting and boiling point. Low melting and boiling point.
Electrons 1 to 3 electrons in the outer shell. 4 to 8 electrons in the outer shell.
Oxygen React with oxygen and form basic oxides. React with oxygen and form acidic oxides.
Acid React with acids and produce hydrogen gas. Do not usually react with acids.

4. They are not malleable and ductile .
5 . They are not sonorous .
6. Oxides of non metals are acid in nature .
7. For example : Carbon , Sodium etc .
OR
Metals : 1. Conductor of heat and electricity .
2 . Malleable : Can be beaten into thin sheets .
3. Possess metallic luster .
4. Solid at room temperature ( except Hg )
Non Metals : 1. Poor conductor of heat and electricity .
2. Brittle : if solids .
3. Donot posses metallic luster .
4. Solids , Liquids or gases at room temperature .
