Germanium (Ge) has 4 valence electrons.
Germanium is located in Group 14 of the periodic table, which is also known as the carbon group. Elements in this group have four electrons in their outermost shell. These electrons are called valence electrons and are responsible for the chemical properties of the element.
In the case of germanium, its atomic number is 32, meaning it has 32 electrons in total. The electron configuration of germanium is [Ar] 3d10 4s2 4p2. The outermost shell, which is the 4th shell, contains 4 electrons (2 in the 4s orbital and 2 in the 4p orbital). These are the valence electrons that germanium uses to form chemical bonds with other elements.
