Solution
Metals :
Metals are the elements that always lose electrons i.e, they are electropositive to achieve the stable electronic configuration of noble gases.
Metals are cations i.e, they are positively charged species
For example, etc.
Non-metals:
Non-metals are those elements that always accept electrons i.e, they are electronegative to achieve the stable electronic configuration of noble gases.
Metals are anions i.e, they are negatively charged species.
For example, etc.
Conclusion :
Metals and non-metals usually form ionic compounds.
The oppositely charged ions are called cations and anions.
Cation is formed by the loss of an electron.
Anion is formed by the gain of electrons.
Normally electron lost by cation is absorbed by anion.
The force which holds these two ions together is known as the electrostatic force of attraction.
The compound so formed is called an ionic bond or electrovalent bond.
Metals always lose one or more electrons and are accepted by non-metals so that both will achieve a stable electronic configuration of the nearest noble gas.
