No a few are cations, including the ammonium ion (NH4+), the hydronium ion (H3O+), and the Mercury I ion (Hg22+).
Yes I think it is (I'm kind of wondering the same thing)
Yes. That's what makes it an ion. If it had no charge it would be a molecule.
No they are not. Polyatomic may refer to an ion, which would be part of an electrolyte or to a molecule which would not.
Yes, except for ammonium
nitrate
Ammonium, NH4+
the role of counter ion in a reaction is it make the complex electrically neutral.
The polyatomic ion represented by the formula NO2- is the nitrite ion.
The sulfate ion (SO42-) is the polyatomic ion
Hydrogen can be an ion, or it can be electrically neutral.
A molecule is neutral, an ion has an electrical charge.
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.
An alumimium atom is electrically neutral and it is an isotope of aluminum.
Nitrate
nitrate
Ammonium, NH4+
the role of counter ion in a reaction is it make the complex electrically neutral.
Polyatomic ions are not compounds because they are not electrically neutral, and they are not elements because they can be broken down into other chemical constituents -- the actual elements.
The chemical formula K2CO3 is for potassium carbonate.
The polyatomic ion for oxide what is it?
An "Ion" is an atom that has gained or lost an electron and is therefore no longer electrically neutral.
