Description
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 (blue) and 30 neutrons (yellow). 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.
