What is the orbital diagram for Ti 2+?
I got 1s two arrows, 2s two arrows, 2p 6 arrows, 3s two arrows, 3p six arrows, 4s two arrows but it is wrong. It said ions of d-block metals typically lack the outermost s electrons that are present in their neutral counterparts.

The electrons in the outermost s orbital of the d-block metals are usually very weakly bound. When a cation forms, the electron(s) in this outermost s orbital are removed. This is because the increase in nuclear charge is more than enough to overcome the electron-electron repulsion and hold the remaining electrons closer to the nucleus. Therefore, when a d-block metal forms an ion, the outermost s electrons are typically removed.
