Answer 2

Answer:

A collection of atoms with a charge is known as a poly atomic ion (positive or negative). For instance, the ions nitrate ion (NO−3), hydroxide ion (OH - ).

Explanation:

Step : 1  The molecules or substances that have a positive or negative charge are known as ions. They fall into three categories: mono atomic, which only has one atom with either a positive or negative charge; diatomic, which contains two atoms; and polyatomic, which contains many atoms.

Step : 2  Therefore, ions having more than two atoms and either a positive or negative charge are considered poly atomic elements.

Step : 3  $\mathrm{NO}_3^{-}$, Given that it contains one nitrogen and three oxygen atoms and has a negative charge, the nitrate ion is classified as a polyatomic ion.

Step : 4   $\mathrm{SO}_4^{2-}$, Given that it contains one sulfur atom, four oxygen atoms, and a -2 charge, the sulfate ion is classified as a poly atomic ion.

Step : 5  $\mathrm{NH}_4^{+}$, Given that it comprises one nitrogen and four hydrogen atoms and a positive charge, the ammonium ion, also known as the ammonium cation, is regarded as a poly atomic ion.

Step : 6  $\mathrm{C}_2 \mathrm{H}_3 \mathrm{O}_2^{-}$, This acetate ion, which comprises two carbon, three hydrogen, and two oxygen atoms with a negative charge, is thought to be a poly atomic ion.
