Hey everyone. I'm reviewing for my chemistry midterm and wanted some clarification on a problem I came across.
The question is...
True or false:
"An element that has an electron configuration of 1s^22s^22p^63s^23p^63d^34s^2 is a transition element"
Now at first I thought it was false because the 4s^2 identifies an alkali earth metal, not a transition element. However, the 3d^3 is throwing me off. What is the significance of the 3d^3 and what element is described by this orbital?

Since the 3 d sublevel is filling, it is in the d block, which makes it a transition metal. Some texts put the 4s before the 3d, some put the 3d before the 4s. Actually because of the overlapping of the energy levels, the 3d sublevel has more energy than the 4s.

I think the 3d3 should come after the 4s2. This element looks like Vanadium and it is a transition metal
