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.
Molybdenium: (K,L,M,N,O) = 2,8,18,13,1or:Mo, complete electron configuration: [1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6] 4d5, 5s1 shorthand: (Kr),5s1,4d5(It is a 4d-block 'transition' element, atom no.42)
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals.
Isotopes of krypton are: Kr-78, Kr-80 to Kr-84, Kr-86. Kr-83 was used in magnetic resonance imaging.

[Kr] 4d10 5s1Just by looking at your periodic table you should see that this element is silver.The [Kr] indicates it follows krypton on the table and you just need to count to '10'+'1' = '11' to come out there.Atom numbers Kr=36, Ag=47, difference 11 (of coarse)

Since it has a -1 charge, it must have 1 more electrons than in the ground state, making the ground state[Kr]5s2 4d10 5p4. This looks like Te (tellurium).
