Answer 1

Answer:

$\bold\red{Ionic\:Compounds}$

• Ionic compound is formed of ions.

• These are formed by combination of metals and non metals.

• The bonds are formed between them are called ionic bonds.

• Ionic bonds are formed by loss and gain of electrons by metals and non metals respectively.

• They conduct electricity in molten state .

• They have crystalline structure.

• They are hard.

• Example are NaCl, KCl , etc.

Answer 2

• They have high boiling and melting point.

• They are hard and brittle.

Additional information :

• Ionic compound is a chemical compound composed of ions.
• Ionic bonding takes place when they held together by electrostatic force.
• They consists of positively charged ions called cations and negatively charged ions called anions.
