Periodic Trends creates periodic tables that use color graphics to visually show trends in the properties of chemical elements. The table shown here uses color, one of three ways to represent the elements' properties. Periodic Trends also creates many types of graphs that show trends in the properties of chemical elements. Gas Particle Motion simulates the kinetic motion of molecules or atoms in the gas phase. Five simulations are provided, showing a typical gas, the effects of volume, mass and temperature, and effusion.
Users can customize or delete the provided simulations and create any number of new simulations.
