Explanation of Solution

Rubidium is in Group IA or 1 and the atomic number is 37.

Rb+ion Indicate that the ion has one less electron than a neutral atom of Rubidium.  The total number of electrons in Rb+ion can be calculated:

37e1e=36eelectronsinRbelectronslosselectronsinRb+

The electron configuration is as follows:

   1s22s22p63s23p6 4s23d104p6

Since Rb+ion is isoelectronic with Kr, Krypton, all 36 electrons of Rb+ion are indicated by the symbol Kr in square brackets.  The shorthand electronic configuration for Rb+ion is [Kr].
