What are Ionic Compounds?

They are compounds containing more than one ions

Example

Sodium Chloride (NaCl) contains 2 ions;

Positively charged Sodium (Na + ) and Negatively charged Chloride (Cl - )

It has equal number of positively and negatively charged ions

So overall charge is 0

A group of atoms chemically bonded together is Here are the valency of a few elements:
called Molecule.

Polyatomic Ions	Ionic Compounds
They are ions	They are compounds
They usually do not exist on their own	They can exist on their own
They are positively or negatively charged	They do not carry any net charge
Ammonium (NH4 + ) is positively charged Chloride (Cl - ) is negatively charged	Sodium Chloride (NaCl) It has equal number of positively charged Na + ions and Negatively charged Cl - ions So overall charge is 0
