Rubidium ion symbol

Rubidium is the 37th element in the periodic table and the symbol is ‘Rb’. Rubidium has an atomic number of 37, which means that its atom has 37 electrons around its nucleus.

The electron configuration of rubidium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s¹ which means that the first two electrons enter the 1s orbital.

Rb ion charge

Since the 1s orbital can hold only two electrons, the next two will enter the 2s orbital. The next six electrons enter the 2p subshell. The p subshell can hold a maximum of six electrons. So first we put six electrons in the 2p subshell and then the next two electrons in the 3s orbital.

Since the 3s is now full, the electrons will move to the 3p subshell, where the next six electrons will enter.

The 3p subshell is now full.

How many valence electrons does rubidium have

Consequently, the following two electrons will enter the 4s orbital. Since the 4s orbital is full, the next ten electrons will move into the 3d subshell.

The 3d subshell is now full. Consequently, the next six electrons will enter the 4p subshell.

Since the 4p is full, the remaining one electron will move to the 5s orbital. Hence
