Electron Configuration of Thorium

Calculate the full and condensed electron configuration of Thorium (Th).

Enter the atomic number or symbol of any element, including those that have not been discovered yet, and this calculator will calculate its electron configuration and other related properties (theoretical, if atomic number > 118).
