orbitals – Atomic subshell / orbital-box diagrams for LaTeX, with automatic electron filling following Hund's rule and the Pauli principle

orbitals draws the familiar box-and-arrow notation for atomic subshells (s, p, d, f). You give only the principal quantum number, the subshell letter and the number of electrons; the package fills the boxes automatically (one spin-up arrow per box first, then pairing), reproducing the high-spin free-atom ground state.

It can draw:

• a single subshell (suborbital)
• a row of subshells (electronconfig)
• a valence configuration with a noble-gas core (atomconfig)
• an empty transition-series template (transitionseries)

Every diagram can be scaled and placed inline in running text. Colours, box size, spacing and arrow shape are configurable.
