Question

discuss the physical properties of metals and nonmetals

Answer 1

Hello buddy..

Metals
****************

Good conductor of heat and electricity..
Malleable and ductile..
Usually hard
Usually have high melting and boiling points...
Lustrous in appearance..

Eg. Gold, silver, etc..

Non metals
*********************

Bad conductor of heat and electricity..
Do not poccess Ductility and malleability..
Usually are not so hard.
Softer than metals
Eg : Sulphur, plastic etc

Hope it helps you buddy

Answer 2

Physical properties of non-metals

Non-metals may be either solids, liquids or gases.

Solid non-metals are brittle and break down into powdery mass on striking with a hammer except diamond which is the hardest non-metal.

They have a dull luster but iodine is lustorous.

They have low melting points except diamond that has very high melting point.

They are poor conductors of heat and electricity except graphite.

They are not malleable.

They are not ductile.

They are not sonorous.

Examples are carbon, Sulphur, oxygen, phosphorous and many more.

Metals have these typical physical properties:

Lustrous (shiny)

Hard.

High density (are heavy for their size)

High tensile strength (resist being stretched)

High melting and boiling points.

Good conductors of heat and electricity.
