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!
Version: 3.02, 2012.
Leaing 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.
