The current version of MC:EE does not display the structure of potassium properly in the element constructor. Potassium should have 4 energy level with 1 electron located at its valence shell. The model displayed in the element constructor display a model showing 3 energy level with valence being added to the 3d orbital. As my students point out, all elements starting from period 4 have incorrect modeling.
