Ions are charged.
molecules
A molecular ion is a type of ion that either has less or more electrons than it has protons. A polar molecule is a molecule that has positive charges near its center and negative charges outside that center.
An ion has an electrical charge.
A hydrogen ion, H+
The number of electrons.
Sulfite is a ion, while Sulfur trioxide is a molecule
Hydroxide ion is a water molecule without the nucleus of one of the hydrogen atoms.
What is the difference between ammonia gas and an ammonium ion?
No, they are covalent bonds. An ionic bond is formed between a group 1 metal and Br.
the difference between a molecule and a compound is the spelling.
An ion is simply a molecule with an uneven number of electrons and protons. Remember that in order for a molecule to be stable, the number of protons (positively charged particles) and electrons (negatively charged particles) must be the same. Ions are different because they gain and lose electrons.
spelling?
An ion is a positively or negatively charged atom or molecule.

A chlorine radical is simply Cl. with no charge but free electrons wanting to bond. A Cl atom basically. A chlorine molecule is Cl2 (two atoms bonded covalently). A chloride ion is Cl-. Many people confuse an ion with a radical. They are not the same.
A molecular ion is a type of ion that either has less or more electrons than it has protons. A polar molecule is a molecule that has positive charges near its center and negative charges outside that center.
