Electrovalent combinations, also known as ionic bonds, occur when atoms transfer electrons to achieve stable electron configurations, typically between metals and nonmetals. In this process, a metal atom donates one or more electrons, becoming a positively charged ion (cation), while a nonmetal atom accepts the electrons to become a negatively charged ion (anion). The electrostatic attraction between these oppositely charged ions results in the formation of ionic compounds, which often have high melting and boiling points and conduct electricity when dissolved in water or molten. Examples include sodium chloride (NaCl) and magnesium oxide (MgO).
