Fun Facts
The existence was predicted by Russian chemist, Dmitri Mendeleev, who developed the periodic table. He said a new element would be found to fill an empty spot in his table because none that were already discovered could be put below silicon since none had properties like it.
Germanium is a metalloid that is in the middle of the carbon family, which is group 14 in the periodic table.
The origin of the element is from the Latin word Germania, meaning Germany.
