👉 The term "submetallic" is a scientific term used in chemistry to describe compounds that have fewer atoms than they would contain if all of their atoms were metallic. This means that the atoms are more likely to be non-metallic, such as carbon or nitrogen, rather than being part of a metallochemical system. For example, in the compound calcium carbonate (CaCO3), one atom is bonded to two other atoms, which makes it submetallic. Similarly, the compound aluminum oxide
