Collisions: Play Chemistry

Bring chemistry to life through play!

Interact with the basic building blocks of chemistry in order to explore and solve challenges.

Atoms: Use protons and electrons to build atoms and explore atomic size.
Ions: Manipulate energy to add or remove electrons and form ions.
Covalent Bonding: Bond atoms to build molecules of various shapes and bond polarities.
Ionic Bonding: Explore how ions of various charges interact to form ionic compounds.
Acids & Bases: Remove protons from acids, then add them to bases while exploring the strengths of various acids.

In the sandbox, freely explore the rules of chemistry and earn achievements along the way.

When ready, enter the challenge levels and use your knowledge to solve the puzzles, using the bank and targets as guides!

Once you’ve mastered the challenges, take it to the next level by solving a puzzle within a puzzle in the later challenge levels to see how it all connects.

Atoms is free to play. Full access to Atoms, Ions, Covalent Bonding, Ionic Bonding, and Acids & Bases are available through monthly or yearly in-app subscription or by using a valid login provided by your school. Educational institutions can contact PlayMada Games for more information.
