Students will have fun constructing simple molecules with this simulation, while also gaining insight about how to read molecular formulas. Click and drag atoms to see which ones bond to form diatomic molecules (composed of a pair of the same element.) Drag different atoms into the field to build a more complex molecule composed of different elements. After a molecule is built, it can be viewed in 3D models.

This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

Please note that this resource requires Java Applet Plug-in.
Editor's Note: This resource is appropriate for grades 6-12, with teacher adaptation. Basic concepts of molecular structure should be comprehensible in the middle grades. Students will recognize that the subscript in the molecular formula indicates the number of that atom in the molecule, and the coefficient indicates the total number of molecules. High school teachers may wish to introduce covalent bonding and electron sharing.

4. The Physical Setting

4D. The Structure of Matter
  • 6-8: 4D/M1a. All matter is made up of atoms, which are far too small to see directly through a microscope.
  • 6-8: 4D/M1b. The atoms of any element are like other atoms of the same element, but are different from the atoms of other elements.
  • 6-8: 4D/M1cd. Atoms may link together in well-defined molecules, or may be packed together in crystal patterns. Different arrangements of atoms into groups compose all substances and determine the characteristic properties of substances.
  • 9-12: 4D/H7a. Atoms often join with one another in various combinations in distinct molecules or in repeating three-dimensional crystal patterns.
  • 9-12: 4D/H7b. An enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules.
  • 9-12: 4D/H8. The configuration of atoms in a molecule determines the molecule's properties. Shapes are particularly important in how large molecules interact with others.

10. Historical Perspectives

10F. Understanding Fire
  • 9-12: 10F/H3. In the early 1800s, British chemist and physicist John Dalton united the concepts of atoms and elements. He proposed two ideas that laid the groundwork for modern chemistry: first, that elements are formed from small, indivisible particles called atoms, which are identical for a given element but different from any other element; and second, that chemical compounds are formed from atoms by combining a definite number of each type of atom to form one molecule of the compound.

11. Common Themes

11B. Models
  • 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
  • 6-8: 11B/M4. Simulations are often useful in modeling events and processes.
