Question

compare the physical property of metal and non metal give an exception in each case

Answer 1

Answer:

We can diffrentiate the metal and non metal on the basis of the following physical properties__

1.malleability 》

Metals are malleable (beaten into thin sheets) WHILE non metals are not malleable or brittle.

2.ductility》

metals are ductile (drawn into thin wires) WHILE non metals are non ductile.

3.good and bad conductors of heat and electricity》

metals are good conductor of heat and electricity WHILE non metals are bad conductor of heat.

EXCEPTION-A form of carbon element called diamond and another form of carbon element called graphite are non metals but these are good conductor of heat and electricity respectively.

4.lusture》

Metals are lustrous WHILE non metals are non lustrous or dull in appearance.

EXCEPTION-non metal like iodine is however lustrous or shining appearance.

5.hardness or softness》

Metals are generally hard. WHILE Non metals are generally soft.

EXCEPTION-metals like sodium and pottasium are soft and can be cutted by a knife.

And diamond is a non metal which is hard (even diamond is the hardest natural substance known).

6.physical state at room temperature》

Metals are solid at room temperature WHILE non metals can be in solid liquid or gaseous state.

EXCEPTION- mercury is the only metal at room temperature.

Answer 2

Answer:

Metals

In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

These metals have properties that you normally associate with the metals you encounter in everyday life:

They are solid (with the exception of mercury, Hg, a liquid).

They are shiny, good conductors of electricity and heat.

They are ductile (they can be drawn into thin wires).

They are malleable (they can be easily hammered into very thin sheets).

All these metals tend to lose electrons easily. The following figure shows the metals.

Nonmetals

Except for the elements that border the stair-stepped line, the elements to the right of the line are classified as nonmetals (along with hydrogen). Nonmetals have properties opposite those of the metals.

The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity.
