The electron configuration of strontium is 1s22s22p63s23p63d104s24p65s2.
[Kr] 5s2
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
The noble gas configuration for Sr (strontium) is [Kr]5s2
Sr, Strontium (atom no. 38)
