[QUOTE="Clara Chung, post: 5588593, member: 550045"] Thanks for telling me that an atom from a metal has different properties from a metal. So work function is a term for a solid only? If I consider an atom only, is "threshold frequency * h" or "energy to cause the first ionization "= The energy needed to raise an electron from the highest energy level to infinity? thanks a lot [/QUOTE]
