charges/ions

• An ion is the result or outcome of an atom gaining or losing an electron
• Isotopes almost share the same chemical properties (family of an element) same amount of protons and different amount of neutrons.
• Metal lose electrons to get a full outer shell and become positive ions
• Positive ions have more protons than electrons
• Non-metals gain electrons to get a full outer shell, they become negative ions
• Negative ions have more electrons than protons
• An ion is an atom that has gained or lost electrons to get a full outer shell of electrons to become chemically stable
• Ions have a different number of protons than electrons
