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. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.

Facts about the Discovery and History of the Germanium Element
Germanium was discovered by Clemens Winkler in Germany in 1886. Mendeleev called it "ekasilicon"

What is Germanium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Germanium is just one element that can be found.
