Subshells

Denser dots mean an electron is more likely to be found there. Subshells take turns in focus; select one to hold it.

How the electrons fill in

Visible emission lines

Observed lines of the neutral atom from 380 to 750 nm, up to the 40 strongest. The tube colour mixes lines by intensity and is illustrative. Data: NIST ASD.

The cloud is a sketch of probability density: shapes come from hydrogen-like orbitals, sizes from Slater's rules, and radii are square-root compressed. The nucleus is not to scale. Tap the nucleus to add a proton.

Temperature

Phase
Crystal structure
Root-mean-square speed

On the thermometer, the green ring marks melting (or sublimation) and the ochre ring marks boiling. Drag the thermometer or the slider to change the temperature.

Particle motion is a sketch: solids vibrate per the Lindemann criterion, liquids and gases use simplified short-range forces, and speeds are compressed from the rms speed. The red-hot glow above about 800 K follows a blackbody spectrum.

Demonstrations are illustrative: apparatus and phenomena follow real behaviour, while particle motion and timing are simplified. Nuclear timescales are compressed logarithmically from the half-lives.
