The propensity of an atom to donate electrons and form positively charged cations is known as electropositivity.
The majority of metallic elements, especially alkali metals and alkaline earth metals, exhibit electropositivity.
Alkali metals are thought to be the most electropositive elements in the periodic table.
The most stable element that is most electropositive is known to be cesium.
In the modern periodic table, electropositivity rises down groups and falls across periods.
