Problem: What noble gas has the same electron configuration as the ion in the following compound?a. cesium sulfide

FREE Expert Solution

We are asked what noble gas has the same electron configuration as the ion in cesium sulfide

The formula of  cesium sulfide is Cs2S which are formed by the ions

Cs2S → 2 Cs+ + S2-


You can determine the ground-state electron configuration of Cesium (Cs) by referring to the periodic table and locating the position of Cs in the periodic table.

Ground-state means that the element is in its lowest energy form (not in excited state). Ca has no charge which means that no electrons are removed or added in the atom.
