I have a basic confusion regarding polyatomic ions:
Is it meaningful to say "which atom" in a polyatomic ion is charged?
Consider for instance hydroxide OH$^-$:
The oxygen has greater electronegativity than the hydrogen, so it is "more negative" than the hydorgen.
However, I am not sure: Is it wrong to say that the hydroxide is composed of a neutral hydrogen together with a negatively charged oxygen?
I guess this won't be an accurate statement/description, right?
In particular, If I understand correctly, then the formulas OH$^-$ and HO$^-$ describe exactly the same diatomic anion, so in particular on cannot deduce from the formula which is the more negatively charged atom between $H$ and $O$. (For a moment I wasn't sure whether the presence of the minus sign above the $H$ in OH$^-$ means that it's the $H$ that is more negative).
