What element is represented by this electron ground state configuration :

[Kr] 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d2 7s2

Is this really Krypton?


    No, [Kr] means all of the shells up to and including Kr are filled in so you have the 36 electrons for Kr PLUS all of the other electrons shown.
