All ions are charged- either positive or negative - there is no such thing as a neutral ion- an ion is a charged atom e.g. Na+ (sodium atom lost 1 electron), Cl- (chlorine atom gained 1 electron) or a molecule (chemists call these polyatomic ions) - e.g. SO42-

What is meant by the term ion when a sodium changes from an atom to an ion?

An ion is a charged particle. A sodium atom is neutral and has one electron in the valence shell. When it loses its valence elctron, it is no longer neutral and becomes Na+ , i.e a charged particle, hence it is an ion.
