Closed electronic shell

Ti4+ has a "closed electronic shell"?

What does that mean??

Write down the electronical configuration of Ti4+. Compare this with Argon.

Okay, it means it has the same electronic configuration of Argon. So "closed electronic shell" means very stable electronic configuration where further addition or loss of electron from Ti4+ is difficult, right?

What I was asking is what is so special about "closed electronic configuration".

The addition of electron is no problem. Ti3+ and Ti2+ are also existing. Loss of electrons is not possiible.

So the term "closed" only means it has a noble electronic configuration, nothing special?

"Open" means "not closed" then, right?

There are some implications for spectroscopic transitions involving transition metal centers.
