With this revolutionary approach to teaching chemistry, you can make your own happy atoms! This physical and digital system lets you discover the world of molecules in an intuitive, hands-on way. 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. 
 
The digital component takes this molecular modeling system to the next level. Using the Happy Atoms app and the camera on your tablet or smartphone running iOS or Android, you can scan molecules you build. The app then uses state-of-the-art image recognition technology to identify the molecules.
