Build an Atom
This simulation allows you to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can then play a game to test their ideas. Curriculum links include: • Atoms • Atomic Structure • Isotope Symbols • Atomic Nuclei Sample learning objectives include: *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.
