It loses or gains one or more electrons.

An ion is an atom which has an electrical charge, beacause it has either lost some of the electrons or received extra electrons (electrons are negatively charged). Ions can be created by chemical reactions. Some atoms actually prefer to be ions in the sense that they can lower their energy by receiving one or more electrons (chlorine is an example). For instance sodium can react with chlorine to form sodium chloride which consists of positively charged sodium ions and negatively charged chlorine ions. That's because the energy it costs to move the outer, loosely bound electron from sodium is less than the energy gained by putting an extra electron on the chlorine atom.
Hope that helps - otherwise maybe you should clarify the question.

when bonding with another atom, it will gain or lose electrons to make both atoms more stable, this will make it a positive ion if it loses electrons and negative if it gains

there is two ways
1-when the atom loss electron from the outer shield and became positive ion
2-when it gain electron to be more stable-and became negative ion
Good luck

when it has more protons(which will make it positive charge) than electrons or vice versa in which case it will be negative charge they gain these protons or electrons by bonding
