How are ions formed?
How are isotopes formed?
Distinguish between an ion and an isotope.
Ions: Electrons being gained or lost (changes CHARGE, but not mass)
Isotope: Neutrons being gained or lost (changes MASS, but not charge)

What distinguishes an ionic bond from a covalent bond?
Ionic: Electrons are transferred.
Covalent: Electrons are shared.
