Each electron has a set of quantum numbers that specify it's location, orbital, and energy in a unique manner.

When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...

The atoms around you have existed for billions of years- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form...

Kids learn about the element mercury and its chemistry including atomic weight, atom, uses, sources, name, and discovery. Plus properties and characteristics of mercury.

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

Interactive concept animation shows the atomic number, weight, and structure of the first eleven elements of the Periodic Table of Elements.
