2. Simple ions Those ions which are formed from single atoms are called simple ions

3. Examples Magnesium ion M g2+, A luminium ion A l3+, O xide ion O2–, C hloride ion C l– S odium ion, N a+, is a simple ion because it is formed from a single sodium atom, N a.

4. Simple ions are also known as monoatomic ions .

5. Those ions which are formed from groups of joined atoms are called compound ions . COMPOUND IONS

6. For example, ammonium ion NH4+, is a compound ion which is made up of two types of atoms joined together, nitrogen and hydrogen. Similarly, carbonate ion CO3 2–, sulphate ion SO4 2–, nitrate ion NO3– and hydroxide ion OH–, etc., are all compound ions.

7. Compound ions are also known as polyatomic ions .
