    1. The problem statement, all variables and given/known data
    Just wondering where does a 7s orbital come into play?
    Would you use 7s when it comes to francium?

    2. Relevant equations


    3. The attempt at a solution

    If the (b) part of the exercise is "Why is this so?", we're in trouble :smile:

    Don't forget about excited states. Francium is not used much because it has a lifetime too short to do meaningful experiments with it, but the 7s orbital comes into play often when dealing with cesium.
