32 the valence electron of which atom in the ground state has the greatest amount of energy? (1) cesium (3) rubidium
(2) lithium (4) sodium

Answer;

Cesium

Explanation;

-Cesium atoms have 55 electrons and the shell structure is 2.8.18.18.8.1. The ground state electron configuration of ground state gaseous neutral cesium is [Xe].6s1. The atom has a valence of 1, meaning it requires to loose one electron to form a stable configuration. Compared with alkali metals lithium rubidium and sodium its atom has the greatest amount of energy at ground state.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
