Ions with 18 electrons

WebAdult Education. Basic Education. High School Diploma. High School Equivalency. Career Technical Ed. English as 2nd Language. 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 number of electrons is unequal to its total number of protons.
