An ion is formed by either adding electrons to or subtracting electrons from the atom. This changes the balance between the positive protons in the nucleus and the negative electrons orbiting around it, resulting in a charged particle. Adding or subtracting protons or neutrons would change the identity of the atom itself and result in a different element, not an ion.
