Detailed Solution

The periodic table contains transition metals, alkali metals, and alkaline earth metals, which are known as metals because they conduct heat and electricity and are similar to copper and aluminium. Non-metals, on the other hand, are poor conductors of electricity and include all halogens, carbon, sulphur, noble gases, etc.

The following are the main distinctions between metals and non-metals:

Metals	Non-metals
They form ionic compounds	They usually form covalent compounds
Metals have low ionization enthalpies	Non-metals have high ionization enthalpies
The majority of the time, metals are more electropositive and less electronegative	Non-metals are electronegative
Metals have less negative electron gain enthalpies	Non-metals have high negative electron gain enthalpies
Metals have the ability to lose electrons easily	Non-metals cannot lose electron easily
The tendency for metals to gain electrons is less	Non-metals can easily gain electrons
Metal oxides are basic in nature	Oxides of non-metals are acidic in nature
Reducing power of metals is high	Reducing power of non-metals is low
Metals forms cations	Non-metals form anions
