Using a set of 50 atom models representing 16 different elements, you can assemble your own molecular models. The atoms connect easily with magnets: metal tips on the ends of rubbery arms, which represent free electrons, snap onto magnetic bonding sites on the atom spheres, which represent empty spots for electrons in the atom’s outermost electron shell. Because the atoms already have the correct number of free electrons & empty bonding sites, it is difficult to build a molecule that doesn't actually exist. Using the Happy Atoms app & a tablet/ smartphone camera, you can scan molecules you build. Through state-of-the-art image recognition technology, the apps identifies the molecule, presents information about it, including its composition, usage, properties, hazards, formula, and structure.
