Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
Build an atom with protons, neutrons, and electrons to understand its element, charge, and mass.
Explore the Build an Atom simulation. Click on the + sign for each of the boxes (element name, net charge and mass number) to view changes as you change the number of particles in the atom.
An interactive simulation to learn building an atom with protons, neutrons, and electrons, and understand its element, charge, and mass.
