Question

6)Which Is not a polyatomic ion? a.Ammonium b.Nitrate c.Carbonate d.None of the above​

Answer 1

Answer:

(d) none of the above

Explanation:

ions which are consist of one or more atom are called polyatomic ions. atoms in a polyatomic ions are generally covalently bonded to each another, and hence stay together as a single, charged unit.

Here,

Ammonium (NH₄⁺) has one nitrogen and 4 hydrogen atoms

Nitrate (NO₃⁻) has one nitrogen and 3 oxygen atoms

Carbonate (CO₃⁻²) has one carbon and 3 oxygen atoms

So, all these are polyatomic ions. Hence the correct option will be (d) none of the above
