7-4-7-6 Atoms are made of protons, with positive charges, and electrons, with negative charges. When an atom, usually of a metal, loses an electron, it becomes an '''ion''' with a positive charge. When an atom of a non-metal gains electrons, it becomes a negative ion. The charge of the ion is determined for metals by subtracting the number of electrons from the number protons and vice versa for non-metals. '''Example''' Sodium (Na) ion with 11 protons and 10 electrons. The '''net charge''' is thus: 11 protons....11+ -10 electrons..10- ___________________ Net Charge= +1 Therefore the ion is labled Na<sup>+1</sup>
