Build an atom

Learning objects Build an atom

TLF ID M019538

This interactive simulation explores atomic structure, elements and the periodic table. In a series of simulations students 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; and generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons. The resource does not require registration to access the simulation for students to use, however teachers can register for free access to tips and additional instructions for using the resources and a range of teacher-submitted activities that use the simulation. The simulation is also available in multiple languages.
