Create your own happy atoms & explore the world of molecules with this Happy Atoms Introductory Set from Thames & Kosmos!

This hands-on science kit provides an innovative approach for introducing and teaching chemistry to kids. They can use the 17 atom models inside to build hundreds of their own molecular models; the atoms combine with the user-friendly magnetic metal tips at the ends of rubbery arms. The corresponding app/digital system lets curious learners explore molecular structures, take guided tests, and more!

Build up to 17,500 molecules with the best-selling Happy Atoms Complete Set

What makes Happy Atoms different?

Magnetic physical pieces AND a top-rated digital app.

Kids can build, scan, identify, and explore molecules with this engaging molecular modeling system!

With this Happy Atoms Introductory Set, students use 17 atoms representing 6 different elements to build 508 molecules!

What makes these atoms so happy?

While atoms don't have emotions, they do have observable behaviors. And atoms tend to be more stable (happy) with certain numbers of electrons.

Where do they find extra electrons if they need more to be happy? From other atoms that have too many electrons, of course! When atoms share or exchange electrons to be happy, they stick together. Happy atoms form molecules! 

With the Happy Atoms Introductory Set, kids first build models using magnetic connectors. Next they scan and identify molecules using the free app. Finally, students discover molecular usage, hazards, formula, and more.

What’s included in the Happy Atoms Introductory Set?

  • 17 atoms
  • 6 elements
  • 73 activities
  • 508 possible molecules
  • 16-page instruction guide & experiment manual
  • Periodic Table of the Elements poster

What can kids do with the Happy Atoms app?

  • Explore molecular properties, composition & structure
  • Take guided quests to discover & learn about new molecules
  • Collect sets of molecules they've built & explored
  • Use it as a fun, interactive chemistry curriculum

How does the Happy Atoms app work?

  • Using the app & the camera on your tablet or smartphone, you can scan molecules you build
  • The app uses state-of-the-art image recognition technology to identify the molecules
  • After a molecule is discovered, the app presents information about it, including its composition, usage, properties, hazards, formula, and structure 
  • The app can recognize hundreds of the molecules that you can build with this set 
  • It presents detailed information about 52 of the molecules you can build
  • It takes you on guided quests to discover new molecules and learn about them
  • You can track your progress with the app, collecting sets of molecules that you have built and explored

Who should use Happy Atoms?

  • Homeschool families & chemistry classrooms
  • Middle school through college students
  • People who find chemistry complicated or abstract
  • People who can't get enough of chemistry

How are molecules built with Happy Atoms?

  • Rubbery arms with magnetic tips represent free electrons
  • Magnetic sites on the spheres represent empty spots in the atom’s outermost electron shell
  • Snap the metal tips (electrons) to the magnetic bonding sites
  • Atoms include correct number of free electrons and empty bonding sites, making it hard to build a molecule that isn't real

NOTE: The Happy Atoms app is supported by both Android and IOS (iPhone, iPad) devices
