           The Carbon Group








             This group contains one non-metal, two semi-metals, and three metals.

             The non-metal carbon (C) is the main element in all living things. The
             semi-metals – silicon (Si) and germanium (Ge) – are elements that have
             the properties of both metals and non-metals, and they are essential in
             electronics. Two of the metals – tin (Sn) and lead (Pb) – have been used
             by humans for centuries. Flerovium (Fl), an artificial element, has no
             known uses.
