Welcome to Neils Bohr Simulator INTRO The program can only go up to eighteen electrons for the time being, I mainly made this for fun. As electrons get added each energy level starts to fill up, but different energy levels can hold different amounts of electrons. For example, the first level can only hold two electrons. (This is a very simplified explanation) INSTRUCTIONS Use the electron slider to change the amount of electrons, to reset the slider, click the flag.
