Question

How would you build a model that is ionized? What happens if an atom is too ionized? How would you build a model that is radioactive? What happens if the imbalance between protons and neutrons becomes too great?

Answer 1

When the number of electrons does not equal the number of protons, the atom isionized. (The atom is then called an ion). ... If your atom is too ionized, it will likely zip away from you and attach itself to a nearby atom or molecule. An atom becomes radioactive when its nucleus contains too many or too few neutrons.
