Activity 2.2 Orbital shapes in hydrogen Timing: Allow approximately 1 hour and 30 minutes During this activity, you will need to make sketches and notes for uploading to my online notes. These could be made by hand and then photographed, or alternatively, you could use a word processor or simple drawing package on your computer. This interactive allows you to explore the shapes of the electron waveforms in hydrogen. It displays the form of the electron wave, which depends on the quantum numbers , and . When the interactive starts, it is set for the quantum numbers , and , and a blue sphere is displayed. You can select different quantum numbers using the drop down menus for , and . To help you see the forms of the waves you can do the following. Rotate the waveform using your mouse, arrow keys or rotate check box. Choose to remove different 'cut segments' using the radio buttons, so that you can see the interior of the three dimensional waveform. Choose to view different slices through the waveform using the 'slices' radio button and the 'horizontal' and 'vertical' check boxes, which generate various cross-sections of the waveform. (If you need to
