Question

Write the difference between metals and non metals on the basis of its physical state,Malleablity and Hardness.​

Answer 1

Answer:

Metals :

1) most malleable

gold is example

2) generally they are hard except sodium,lithium,etc.

Non-metals:

1)not malleable

2) generally non metals are soft except iodine Crystal's,diamond

Answer 2

$\large \bold{ \underline { \underline{ \: Answer : \: \: \: \: }}}$

$\to$ Metals are generally Solid

$\to$ Metals are malleable

$\to$ Metals are of generally hard

$\to$ Non metal are mostly exist in two of the three states of matter at room temperature

$\to$ Non metals are not malleable

$\to$ Non metals are generally soft

Physical State

$\to$ Metals are solids at room temperature with the exception of mercury , which is liquid at room temperature

Gallium is liquid on hot days

$\to$ Most of the non metals exist in two of the three states of matter at room temperature

Gases (oxygen) , solids (carbon) and only bromine exists as a liquid at room temperature

Malleablity

$\to$ Most of the metals are malleable it is property of metal due to which it can be beaten into thin sheets

Gold and Silver are the most malleable metals

$\to$ Non metals are not malleable i.e they cannot be beaten into thin sheets

Hardness

$\to$ Most of the metals are hard

The hardness varies from metal to metal

Some alkali metals like Lithium , Sodium and Potassium are so soft that they can be easily cut with a knife

$\to$ Most of the non metals are soft diamond , an allotropic form of a carbon is the hardest substance
