Electronic Structures of Atoms and Ions
On this page you can practice constructing electronic structures of atoms and ions. When you press "New Problem", a species will appear in the uppper right frame. Place the electrons in the appropriate orbitals in the top frame, following the rules for electronic structures. To indicate the degree of occupancy of a given orbital, do the following:
When you have finished your answer, press the "Submit" button in the top frame. Results will appear in the table on the main window.
- If the orbital has no electrons leave the cell empty.
If it has a single electron, enter a 1 in the cell.
- If it has a pair of electrons, enter a 2 in the cell.
- Anything other than empty, a 1 or a 2 will cause your answer to be ruled incorrect.
