The electron configuration and the number of unpaired electrons for(b) Ti⁴⁺ is [Ar] [tex]3d^{0} 4s^{0}[/tex] and 3p electrons (are left alone).
Electron configuration of titanium is 1s2 2s2 2p6 3s2 3p6 3d2 4s2.
1. Identify the given element and its atomic number from the periodic table.
2. Write the electron configuration by the energy level and the type of orbital first, then the number of electrons present in the orbital as superscript.
The easiest way to write the electronic configuration for any element is by using a diagonal rule for electron filling order in the different subshells according to the Aufbau principle.
The 3 rules for writing the electron configuration in the orbital box diagram are – the Aufbau rule, the Pauli-exclusion rule, and Hund's Rule.
