Molybdenum (Mo). Diagram of the nuclear composition and electron configuration of an atom of molybdenum-98 (atomic number: 42), the most common isotope of this element. The nucleus consists of 42 protons (blue) and 56 neutrons (yellow). Molybdenum is a transition metal in group 6, period 5, and the d-block of the periodic table. It has a melting point of 2623 degrees Celsius. The transition metal trends are due to electrons filling an inner d-subshell (here, within the 4th ring), shielding the outer electrons from the increasing nuclear charge. | |
