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 chemical symbol for Rubidium-Rb Sulfate-SO4 is Rb2SO4. Rb has a charge of +1 and SO4 has a charge of -2, so in order for the charges to be balanced you need 2 Rb atoms (2 x +1) and 1 SO4 (-2) ion. +2 + -2 = 0
Two: the rubidium ion Rb+ and the nitrate ion NO3-
