103 electrons sit in their real ground-state shells (K 2 · L 8 · M 18 · N 32 · O 32 · P 8 · Q 3 · 8 0 · 9 0 · 10 0). Each orbits and jitters as an agent. Heat or a tap lifts one into a higher shell (up to shell 10); it relaxes back and emits a photon.
Tap near an electron to excite it. The same ?seed= always gives the same run.
LITZ = 103, Lr, Lawrencium. Standard atomic weight 262 (mass number of the longest-lived isotope). Group — (actinide), period 7, f-block.
AMBERGround-state configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 5f14 7s2 7p1 (predicted, not measured; verified 2026-10-10 against the Wikipedia element infobox data, https://en.wikipedia.org/wiki/Template:Infobox_element/symbol-to-electron-configuration, which draws on relativistic calculations. I did not check the primary papers (Lr: 7p1 rather than 6d1, a relativistic effect; experiments are not conclusive)). Shells: K 2 · L 8 · M 18 · N 32 · O 32 · P 8 · Q 3 · 8 0 · 9 0 · 10 0. This is an exception to the Madelung (aufbau) filling order, which would give 7s2 5f14 6d1 at the end.
LITFirst ionization energy 4.9600 eV (NIST).
LITIsotopes: no stable isotope; longest-lived: 255Lr t½ 31.1 sec, 256Lr t½ 27.9 sec, 254Lr t½ 12 sec.
WALLNo emission line is used: the NIST Handbook of Basic Atomic Spectroscopic Data has no strong-lines table for this element, so photons are drawn uncoloured.
WALLShells 8, 9 and 10 are MODEL, Dave’s 10-shell frame: no ground-state atom uses more than 7 shells, so they stay empty unless an electron is excited into them.
AMBERThe orbiting dots are a cartoon (ANALOGY), not orbitals; electron colour is by home shell (q.d), and the nucleus colour is by block (s, p, d, f). The self-check confirms the electron total equals Z, the shell counts sum to Z, every shell is within 2n², and shells 8 to 10 are empty in the ground state; any failure throws.
