Pick an element on the mini periodic table and watch its electrons fill the shells (Bohr model) and orbital boxes according to the Aufbau principle, the Pauli exclusion principle, and Hund's rule. The sim shows the full and condensed electron configuration, the number of valence electrons, period, group, block, and predicts whether the element is a metal or a nonmetal.
