A)
Hydrogen carbonate ion
हाइड्रोजन कार्बोनेट आयन

B)
Phosphate ion
फॉस्फेट आयन

C)
Nitrate ion
नाइट्रेट आयन

D)
Ammonium ion
अमोनियम आयन

​

Answer 1

I think phosphate ion is containing 5 atoms

Answer 2

Answer:

The polyatomic ions which contain five atoms are Hydrogen Carbonate ion (HCO3)- and Phosphate ion (PO4)³-

Explanation:

Polyatomic ions are ions which contain more than one atom.

In Hydrogen Carbonate ion we have 1 Hydrogen, 1 Carbon and 3 Oxygen atoms, totalling to 5 atoms.

Similarly, in Phosphate ion we have 1 Phosphorus atom and 4 Oxygen atoms, in all 5 atoms.
