Periodic Table Group and Classification of the of the Germanium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Germanium is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as one of the Metalloids has the properties of both metals and Non-Metals.
