For example the sodium cation, Na+.
An ion is an atom with a couple of extra electrons, or which is missing a couple. So when common table salt (NaCl) dissolves in water, it comes apart as a positively charged sodium ion Na+ which is missing an electron, and a negatively charged Cl- ion which has the extra electron from the sodium atom.
An ion is an atom or molecule which has either gained an electron or lost one so that it is no longer neutral.
A hole is a place where an electron is missing. If an electron moves into that places, the electron will be missing somewhere else - the hole has moved along.A hole is a place where an electron is missing.

An atom is a particle that has the same number of protons as electrons. For example sodium. A sodium atom has 11 protons and 11 electrons. A sodium ion might have 11 protons and 10 electrons, so it would have a charge of +1. If a sodium ion had 10 protons and 11 electrons, it would have a charge of-1.
If an ion gains an electron that means the ion will be negatively charged.The name of that ion is called anion. On the other hand, if it loses and electron the ion will be positively charged, and the name of that ion is called cation.
an ion
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
A sodium ion is a sodium atom missing one electron. A chlorine ion is a chlorine atom with an extra electron. A salt molecule is a sodium ion stuck to a chlorine ion.

So when common table salt (NaCl) dissolves in water, it comes apart as a positively charged sodium ion Na+ which is missing an electron, and a negatively charged Cl- ion which has the extra electron from the sodium atom.
Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.
The free radical has an an unpaired electron (example OH.); the ion gain an electron to avoid the situation of an unpaired electron (example OH-).
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
An ion is an atom or molecule which has either gained an electron or lost one so that it is no longer neutral.
A Cation is a positive ion formed after removal of electron(s). For example, Fe^+2
Hydrogen with its electron missing is a positive ion and like all ions is very chemically active, trying to become uncharged again.
when an atom loses or gain an electron, it form an ion. similarly, a molecule may also lose or gain an electron to form a molecular ion. example., CH4+
