Metallic compounds are substances formed when metal atoms bond with non-metal atoms or other metal atoms. These compounds often exhibit unique properties, such as electrical conductivity, malleability, and ductility, which are characteristic of metals. Common examples include metallic oxides, metallic halides, and metallic sulfides. In metallic compounds, the metal atoms typically lose electrons, forming positive ions, while non-metals gain electrons to become negative ions. This transfer of electrons creates ionic bonds, resulting in a stable compound. The arrangement of atoms in these compounds can lead to various physical and chemical properties, making them essential in many industrial applications.
