Description

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

Sample Learning Goals

  • Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.
  • Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.
  • Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.
  • Define proton, neutron, electron, atom, and ion.
  • Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.
