The bipositive ion of strontium takes the electron configuration of xenon.
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
Be3+ has only 2 valence electron and not 8.
There is no noble gas configuration for hydrogen.
