Is Ge a cation or an anion?

Answer 1

Ge germanium does not form cations - it is a metalloid and bonds covalently. Under normal conditions it does not form anions, however it can form cluster anions (Zintl ions) in liquid ammonia when reacted with an alkali metal, e.g Ge42-

Answer 2

Ge is typically a cation. As an element, germanium tends to lose electrons to achieve a stable electron configuration, forming positively charged ions.
