Silver (Ag). Diagram of the nuclear composition and electron configuration of an atom of silver-107 (atomic number: 47), the most common isotope of this element. The nucleus consists of 47 protons (red) and 60 neutrons (blue). Silver is a transition metal in group 11, period 5, and the d-block of the periodic table. It has a melting point of 962 degrees Celsius. The trends across the transition metals are due to electrons filling an inner d-subshell (here, within the 4th ring), shielding the outer electrons from the increasing nuclear charge.
