Hi MIke
Here's what Merriam-Webster says
ION
1 : an atom or group of atoms that carries a positive or negative
electric charge as a result of having lost or gained one or more
electrons
2 : a charged subatomic particle (as a free electron)
So all atoms that are charged are ions but not all ions are charged
atoms.
interesting
