Document Summary

** if an external magnetic field does not exist, it is enough information to simply state how far the electron is from the nucleus. As said above, in the absence of an external magnetic field: Although subshells have numerical designations, we also assign them letter codes. ** note that after #3, the letters continue in alpha order. No two electrons in the same atom can have the same set of four quantum numbers . This sets the maximum number of electrons that can occupy a given subshell. Also, there is a maximum occupation for electrons based on the l-value given: (shown below) Furthermore, there is a chart of possible shell/subshell combinations: (shown below) ** 7p^6 is the highest necessary to describe the entire (current) periodic table. In chem 1101, only electron configurations for ground states of real. Electrons tend to occupy the lowest available electron states possible. atoms are addressed.
