U.S. Army STARS Elements is a fun and exciting way to learn chemistry. Build your own atom, play a game to help you learn about chemical bonds, explore the periodic table, and test your chemistry knowledge. Elements is great for students, teachers, and anyone interested in chemistry.

U.S. Army STARS Elements includes...

Atom Builder - A simple, powerful tool that let’s you construct and discover atoms. Add and subtract protons, neutrons, and electrons and see, in 3D, what you can create.

SmashBond - Use the octet rule to bond elements and score points in SmashBond. Swap elements to make 2, 3, or 4 element bonds, and grab bonuses to get a SMASHBOND. It’s a really fun way to help you become familiar with the octet rule and learn common chemical bonds by their type, symbol, name and Lewis dot diagram.

Periodic Table - Use the table to view trends and detailed information about each of the 118 elements. See an interactive Bohr’s model and learn interesting facts about the elements. It’s like a regular periodic table, but interactive and fun.

STARS Challenge - When you’re ready to test your knowledge, take the STARS Challenge. You’ll be presented with questions in 3 areas (elements, bonding, and atomic configuration). Can you master them all?

No matter what your level of experience with chemistry, U.S. Army STARS Elements makes learning fun.

Easy to use lesson plans and teacher guides are available at to help integrate Elements into the classroom.
