Germanium is the third element of the fourteenth column of the periodic table. It is classified as a metalloid. It is similar in properties to the other metalloids near it in the periodic table which are silicon and arsenic. Germanium atoms have 32 electrons and 32 protons with 4 valence electrons in the outer shell.
