Which statement is true about oh− ?

it is a polyatomic anion because it has more than one atom and a negative charge.

it is a polyatomic anion because it has more than one atom and a positive charge.

it is a polyatomic cation because it has more than one atom and a negative charge.

it is a polyatomic cation because it has more than one atom and a positive charge.

Im gonna say A. because anions are negative atoms. OH- is negative, you can tell because of the negative sign. (If it was positive it would be a cation.)

Hope this helps :)

The correct answer is the option A: It is a polyatomic anion because it has more than one atom and a negative charge.

Explanation:

Hello!

Let's solve this!

As we can see the OH- ion, it has a negative charge so we say it is an anion.

When the ion has a positive charge, it is called cation.

We also see that it is polyatomic because it has more than one atom.

When it has only one atom, it is called monoatomic.

After the analysis we conclude that the correct answer is the option A: It is a polyatomic anion because it has more than one atom and a negative charge.
