Notes
Proton count = the element. The outermost shell (valence e) sets the chemistry. e changing level → emits a colored photon = line spectrum.

About Atom

Atom is one of 20 topics in the Matter & Atom domain (10⁻¹⁰ m scale) at My Labs — an interactive simulation atlas. This virtual lab runs right in your browser: adjust the parameters, pick a scenario and watch the phenomenon change in real time, with a click-to-inspect cross-section for every structure.
