What ions are polyatomic?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.

What are polyatomic ions give examples Class 9 answer?
Some examples are: NO−3, this is nitrate ion and it is regarded as a polyatomic ion because there is one nitrogen and three oxygen atoms and it has a negative charge. SO2−4, this is sulfate ion and it is regarded as a polyatomic ion because there is one sulfur and four oxygen atoms and it has a -2 charge.
What is the difference between molecules 2O and O2?
The difference between O2 and 2O is that O2 is a molecule consisting of 2 atoms of oxygen while 2O consists of two separate oxygen atoms.
