Titanium (Ti). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of titanium-48 (atomic number: 22), the most common isotope of this element. The nucleus consists of 22 protons (red) and 26 neutrons (orange). 22 electrons (white) successively occupy available electron shells (rings). Titanium is a transition metal in group 4, period 4, and the d-block of the periodic table. It has a melting point of 1668 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.
