Explanation:
Answer:
The compounds which are formed by the combination of two oppositely charged atoms are ionic compounds.
Explanation:
1. Ionic compounds are formed from two oppositely charged particles, positive and negative.
2. Positively charged particles are cations.
3. Negatively charged particles are anions.
4. As both particles are oppositely charged, they both are attracted towards each other.
5. The force which is responsible for this attraction is called ionic bond.
6. The particles arranged in the ionic compounds are so close to each other.
7. Smaller the place between two particles, the compound becomes more solid.
8. Hence, ionic compounds are solid.
9. There is a large intermolecular force between those particles of ionic compounds.
10. Due to this large force, they become hard in nature and can't be broken easily.
Hence,
Ionic compounds are solid and hard.

Additional Information:
1. Element:
Any substance which is found in the nature in its pure form is called element.
Example: Oxygen ( O ), Calcium ( Ca ).
2. Atom:
The smallest part of an element is an atom.
3. Ions:
When an atom reacts with other atom, ions of that atom are formed.
Example:
Sodium atom ( Na+ )
Chlorine atom ( Cl⁻ )
4. Compound:
When two or more elements react with each other, a compound is formed.
Example:
Water ( H₂O )
Sodium chloride ( NaCl )
