Description
Nickel (Ni). Diagram of the nuclear composition and electron configuration of an atom of nickel-58 (atomic number: 28), the most common isotope of this element. The nucleus consists of 28 protons (red) and 30 neutrons (blue). 28 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). Nickel is a transition metal in group 10, period 4, and the d-block of the periodic table. It has a melting point of 1455 degrees Celsius. The trends across the transition metals are due to electrons filling an inner d-subshell (here, within the 3rd ring), shielding the outer electrons from the increasing nuclear charge.
