Question

How many valance electrons does Cs+ have

Answer 1

Valance electron in
`Cs^(+)` will be zero

Step-by-step explanation:

We know that atomic number of cesium is 55

The electronic configuration of Cs

`1s^2,2s^2,2p^6,3s^2,3p^6,3d^(10),4s^2,4p^6,4d^(10),5s^2,5p^6,6s^1`

Currently therte is one valance electron in Cs

We have given
`Cs^(+)` + sign indicates that cesium losses one electron means now it have no valance electron.

So valance electron in
`Cs^(+)` will be zero
