Atomic Structure and Periodicity

~60 min · 15 stations

Atomic Structure and Periodicity is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify subatomic particles within the atom; trace the evolution of atomic models; calculate relative mass of common isotopes.

Conductor

The Conductor

Welcome aboard the atomic express. We are diving deep into the subatomic realm where matter finds its order. Keep your eyes on the orbitals as we navigate the periodic landscape.
