Question

Considering the electron configurations for Cs(cesium), what ion charged state would it form?

Answer 1

Considering the electronic configuration of cesium, it will form +1  ion charged state.

Explanation:

The atomic number of Caesium is 55

Its electronic configuration is given by

$1s^2\ 2s^22p^6\ 3s^23p^63d^{10}\ 4s^24p^6\ 4d^{10}\ 5s^25p^66s^1$

The final shell contains 1 electron and it will be easier for cesium atom to lose this electron in order to attain stable configuration.

After losing 1 electron, it attains a charge of +1.
