The electronic structure of the Titanium 2+ ion is confirmed to be [Ar]3d24s0. This conclusion is based on the understanding that the 4s orbital is of lower energy than the 3d orbital, leading to the removal of electrons from the 4s subshell first during ionization. The discussion emphasizes the importance of energy efficiency in determining electron configurations for transition metals.
PREREQUISITESChemistry students, educators, and professionals in materials science or inorganic chemistry who are interested in the electronic properties of transition metals.
That's right. 4s is of lower energy than 3d.Max Eilerson said:Titanium 2+ Ion.
Is it [Ar]3d^04s^2
or [Ar]3d^24s^0
I'd assume it's the former (looks more energy efficient).
