Caption

Terbium (Tb). Diagram of the nuclear composition and electron configuration of an atom of terbium-159 (atomic number: 65), the most common isotope of this element. The nucleus consists of 65 protons (red) and 94 neutrons (blue). Terbium is a lanthanide in period 6, and the f-block of the periodic table. It melts at 1356 degrees Celsius. The trend across the lanthanide series arises from the failure of electrons filling an inner f-subshell (here, within the 4th ring) to shield outer electrons from increasing nuclear charge.
