Simulator Atomic Electron Configurations and Orbital Diagrams Go to the following site: Atomic Electron Configurations Simulator Read the how to and then click on “energy ladder” in the top right corner Put the correct amount of electrons in each energy level (only for the atoms below) Click on check answer to see if you are correct If correct, click on the next element across the top Using the simulator, complete the energy ladder for the following elements. Write down the electron configuration and orbital diagram for each.
