electron configuration Ac

Question

abb0t · Answer

Lanthinides are strange, but you should be able too look it up online on wikipedia. It's not usual to work with lanthinides in HS or even undergraduate chemistry courses.

from what I understand it is part of the "f" orbital, which you subtract 2 from the periodic row which it's found. this would result in an answer of 7s2, 5f1... however the answer I should be getting is7s2, 6d1. I was under the impression that Ac was part of the "f" orbital...???

abb0t · Answer

It could be because actinium is often considered a transition metal, having a d-orbital rather than f? That's what I would think.

anonymous · Answer

so then what happens to the elements 71 through 80 and 103 through 114 if we treat the lanthanide series and actinide series as "d" orbitals....

abb0t · Answer

Not all. Just Ac.

So... how would we define the electron configuration of Lr? it can't be the same as Ac.

anonymous · Answer

Lr is defined as 5f14, 6d1, 7s2
