Happy Atoms Introductory Set (17 Atoms)
Using a set of 17 atom models representing 6 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.
With the Happy Atoms Introductory Set, you can snap together hundreds of different molecules. Because the atoms already have the correct number of free electrons and empty bonding sites, it is difficult to build a molecule that doesn't actually exist. Happy Atoms function like the building blocks of the universe!
