Difference Between Metals And Non-Metals


difference between metals and non-metals


If you don’t have any idea about characteristics of metals and non-metals, it is difficult to you to differentiate between metals and non-metals. Usually, it is known as metals are solid because they are hard, lustrous and opaque. On the other hand, non-metals can be solids or gasses. In the non-metals, the metallic properties are absent. Therefore, if we want to differentiate between metals and non-metals, it is necessary for us to get an idea about the characteristics of metals and non-metals. Here, we will discuss difference between metals and non-metals.

Definition Of Metals


Metals are opaque and lustrous elements that can conduct heat and electricity. These metals are ductile and malleable and they are also denser than other elements.

Definition Of Non-Metals


Non-Metals are those elements which don’t have characteristics of metals. These non-metals have low melting and boiling points. These elements are less dense than metals.

Difference Between Metals And Non-Metals

difference between metals and non-metals gif


Metals and non-metals are different from one another in various ways. Their differences are explained below;

Meaning

difference between meaning of metals and non-metals


There is a specific difference between meanings of metals and non-metals. The meaning of metals is that metals are referred to such elements that are hard, shiny and dense. On the other hand, non-metals are those elements that are soft, non-shiny and brittle in nature.

Nature

nature of metals and non-metals

The nature of the metals is electropositive whereas nature of the non-metals is electronegative.

Structure

structure of metals and non-metals


The structure of the metals is crystalline. It means that it forms a crystal lattice that extends in all directions. On the other hand, structure of non-metals is amorphic. It means that it doesn’t have any defined shape.

Physical state

physical state of metals and non-metals


Most of the metals are solids whereas non-metals can be solid or liquid. It means that metals are solids at the room temperature whereas non-metals can be solid or liquid at the room temperature.

Place in the periodic table

place of metals and non-metals in periodic table


There is also a difference between the places of metals and non-metals in the periodic table. In the periodic table, metals are placed on the left side whereas; non-metals are placed on the right side.

Density

density of metals and non-metals


Density means that mass per unit area. The density of the metals is very high. On the other hand, density of the non-metals is very low.

Conduction

conductivity of metals and non-metals


Metals are good conductors of electricity and heat. Therefore, we can say that all the metals are conductors. On the other hand, non-metals are not good conductors of electricity and heat. Therefore, we can also say that non-metals are insulators.

Melting and boiling points

melting and boiling points of metals and non-metals


The melting and boiling points of metals are very high. It means that if we want to melt or boil a metal, we have to provide enough heat to the metal. On the other hand, non-metals have low melting and boiling points. It means that non-metals can easily be melted and boiled at lower temperature.

Location in the blocks

location of metals and non-metals in blocks


Metals are located in s, p, d and f blocks. On the other hand, non-metals are located in s and p blocks.

Ductility and malleability

Ductility and malleability of metals and non-metals


Another main difference between metals and non-metals is that metals show ductility and malleability. On the other hand, non-metals don’t show these kinds of properties.

Electrons

free electrons in metals and non-metals


As we know that in order to conduct heat and electricity, there requires free electrons. Metals have 1 to 3 electrons in their outer shell. Therefore, these electrons can easily free themselves and metals can easily conduct heat and electricity. On the other hand, non-metals have 4 to 8 free electrons. It means that there are no chances of free electrons in non-metals. That’s why non-metals are not good conductors of heat and electricity.

Transparency


All the metals are opaque whereas all the non-metals are transparent.

Reaction with oxygen


When we react metals and non-metals with oxygen, we see different kinds of reactions. After reacting with oxygen, metals form basic oxides. On the other hand, when non-metals react with oxygen, they form acidic oxides.

Reaction with acids


When metals react with acids, as a result of this reaction, hydrogen gas is produced. On the other hand, we can observe that non-metals don’t react with acids.

Examples

examples of metals and non-metals


Some essential examples of metals are Lithium and Barium etc. On the other hand, examples of non-metals are iodine and Bromine etc.
