Titanium 2+ Ion electronic structure?

In summary, the electronic configuration of a Titanium 2+ ion is [Ar]3d^2 and it has 2 valence electrons. The 2+ charge on the ion indicates that it has lost 2 electrons, leading to a more stable electronic configuration. The electronic structure of a Titanium 2+ ion differs from that of a neutral Titanium atom, as the ion has lost its 4s^2 electrons. Titanium 2+ ions are important in chemical reactions, especially redox reactions, and are commonly used as catalysts in industrial processes due to their versatile electronic structure.

Titanium 2+ Ion.

Is it [tex][Ar]3d^04s^2 [/tex]
or [tex][Ar]3d^24s^0[/tex]

I'd assume it's the former (looks more energy efficient).

That's right. 4s is of lower energy than 3d.

I can confirm that the electronic structure of titanium 2+ ion is [Ar]3d^04s^2. This means that the ion has lost two electrons from its outermost 4s orbital, leaving it with a full 3d orbital and a half-filled 4s orbital. This configuration is more stable and energy efficient, which is why it is the preferred electronic structure for the titanium 2+ ion.
