Write your answer There are four simple steps to find out the valence electrons for rubidium atom which are:. Step 1: Find the Atomic Number. Step 2: Write Electron Configuration. Step 3: Determine Valence Shell. As we know, the valence shell of an atom can be found from the highest number of principle quantum numbers which is expressed in the term of n and in 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 5s 1 , the highest value of n is 5 so that the valence shell of Rb is 5 s 1.

Step 4: Find Valence Electrons. The total number of electrons present in the valence shell of an atom is called valence electrons, and there is only one electron present in the valence shell of rubidium 5 s 1.

Thus, rubidium has only one valence electron. There are many different ways to find out the valency of an atom which reflects the ability of an atom to bond with other atoms. Valence describes how easily an atom or a free radical can combine with other chemical species. The valency of an atom is determined based on the number of electrons lost, gained, or shared with another atom.
