Electropositivity is an atom’s tendency or willingness to let go its electrons. Electropositive atoms part away more atoms during a chemical bond than the other atom so that they could become stable, or conform to the octet rule. The electropositivity trait is usually identified with metals. This means if an atom is electropositive, it most likely belongs to a metal. Potassium, sodium, magnesium, etc. are examples of such electropositive atoms. On the periodic table, the elements are grouped based on their electropositivity and electronegativity. The electropositivity levels increase from the top right of the table to the bottom left.
