Silver (Ag). Diagram of the nuclear composition and electron configuration of an atom of silver-108 (atomic number: 47),a rare radioisotope of this element. The nucleus consists of 47 protons (red) and 61 neutrons (yellow). 47 electrons (white) bind to the nucleus,successively occupying available electron shells (rings). 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 | |
