Core levels


To successfully build atoms, players must add an equal number of protons and electrons.

When adding electrons to the orbitals, players explore the patterns of electron fill order (Hund’s Rule and Aufbau Principle) and electron configuration.



Players are introduced to the periodic trend of atomic radii by creating atoms of increasing size.
Sandbox
The Atoms Sandbox provides an open-ended and exploratory environment for students to freely build and compare atoms. Design your own extension activities using the Sandbox and encourage your students to earn the built-in Achievements that focus on a specific topic within Atoms.
