How to Build Atoms

  • Adjust protons to change the element (atomic number)
  • Neutrons create isotopes and affect stability
  • Electrons determine the atom's charge
  • Observe individual protons and neutrons in the nucleus
  • Try creating Hydrogen (1p), Helium (2p), Carbon (6p), Oxygen (8p), or Gold (79p)
