Why do alkaline earth metals act as reducing agents?

Alkaline earth metals being highly electro positive tend to form their divalent cations by undergoing oxidation in this process they act as good reductants by reducing the oxidizing agents. read more

Yes because reducing agents mean that they undergo oxidation which is loss of electrons.And alkaline metals have a tendency to form positively charged ions, they are electropositive and so they act as donors of electrons. read more

Although IE 1 values of alkaline Earth metals are higher than that of alkali metals, the alkaline Earth metals IE 2 values are much smaller compared to alkali metals. In alkaline Earth metals, the second electron has to be removed from the monovalent cation, which has one balance electron in the outermost shell. read more
