Cesium forms a positive ion, also known as a cation.
Cesium is an alkali metal located in Group 1 of the periodic table. Alkali metals have a single valence electron that they readily lose to achieve a stable electron configuration.
When cesium loses this electron, it forms a positively charged ion with a +1 charge, written as Cs<sup>+</sup>.
This cation is highly reactive and forms ionic bonds with nonmetals like chlorine, forming compounds like cesium chloride (CsCl).
