Which element does not have a d orbital vacancy?
a. Sc
b. Ti
c. V
d. Fe
e. Zn

Alright, it's obvious that e is true.
However, isn't b. Ti true, too?
The question asks for an element that does not have a D ORBITAL vacancy.
Ti has filled d orbital, and one unpaired electron in p orbital. This means that its d orbital does not have vacancy.

Titanium- 4s2 3d2 so no titanium has two half filled d orbital

I feel stupid...
I saw Thallinium (81) and thought that was Titanium because it said Tl on the periodic table...
Thanks!

Haha, I also made this mistake of reading Thallinium as Titanium!
