Bohr Atom Diagrams (detailed) — free printable diagram

About this illustration

A detailed, fully-labelled Bohr atom diagram poster showing three elements — Hydrogen (H), Carbon (C), and Oxygen (O) — each with a nucleus diagram, electron shell orbits, and a data box listing atomic number, protons, neutrons, electrons, and electron shells. A four-step conceptual flow at the bottom explains shell-filling rules, and a KEY panel defines proton, neutron, electron, nucleus, electron shell, and maximum electrons per shell. Colour-coding: purple for Hydrogen, green for Carbon, orange/red for Oxygen.
