When it loses one or more of its outer electrons.

There is a different between a postive and negative ion. Ion's depend on protons and electrons. If there is 4 protons and 5 electrons , it would make it a negative ion because the extra electron would have no other neutron to pair up with to make it a balance atom. If there is 4 protons and 3 electrons , it would make it a postive ion because the extra proton doesn't have any other electron to pair up to , to cancel it out. When there is an even amount of electrons and protons then the atom would be a balance atom. So therefore it would have no charge. So therefore telling the difference form a postive and negative ion depends on the extra proton or neutron.
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Helium is a neutral atom that has several isotopes and can become an ion.

IONS OS ION ^^A charged atom is called an ion
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
It will become a soft ion.
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
