Question

Write the differences between metal and non-metal under the following heads.
i.) Nature
ii.) State
iii.) Lustre
iv.) Ductility
v.) Malleability
vi.) Conductivity

Answer 1

Hint: The metals have unique properties that they are lustrous and can be beaten into sheets and hammered into wires. The metals are also sonorous and have shiny looks. Metals are mostly solids at room temperature. The non-metals are opposite to metals in almost all of these properties.

Complete Solution :
We all classify the elements present in the periodic table into metals and non-metals.
- There are some specific properties that only metals possess and the same is the case with non-metals. Metals and non-metals are opposite to each other in the properties. For the given heads in question, the metals and non-metals can be differentiated as -

Sr. No.	Property	Metals	Non-metals
1	Nature	Metals are very hard in nature. The Sodium is an exception.	Non-metals are soft in nature.
2	State	Metals are mostly found in solid state at room temperature. Mercury is an exception. It is liquid at room temperature.	Non-metals can be solid, liquid or gases. It can be any state at room temperature but mostly are in liquid and gases states.
3	Lustre	The metals have a shiny appearance. Thus, these are lustrous.	The non-metals have a dull appearance.
4	Ductility	The ductility is the property to beat the substance into thin wires. Metals can be beaten into wires. So, these are ductile.	The non-metals can not be beaten into sheets. Thus, these are non-ductile.
5	Malleability	The malleability is defined as the property of a substance to be hammered and beaten to thin sheets. This is characteristic of metals. So, the metals are malleable.	The non-metals on the other hand are non-malleable. These can not be hammered into sheets.
6	Conductivity	Metals are good conductors of electricity and heat.	Non-metals are bad conductors of electricity and heat.

So, the above table explains all the heads mentioned in the question.

Note: The metals are the elements that can donate electrons easily to achieve noble gas configuration. Almost all s-block elements are metals and almost all non-metals belong to p-block. However, there are some metals present in p-block. Then, the d-block contains transition elements. There is a transition actually from metals to nonmetals. Those elements which are near s- block have more metal character and then there are even metalloids.
