An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total … Meer weergeven The word ion was coined from Greek neuter present participle of ienai (Greek: ἰέναι), meaning "to go".
