1E.25 Part C

[Letty Liu 2C]

For part c, it asks for the notation of Group 5 transition metals. Don't these elements have 3 valence electrons? Shouldn't the answer be (n-1)d^3 ns2?

I think what they mean by group 5 transition metals is specifically the fifth group of the transition metals, not the fifth group of the periodic table. If you take it as being the fifth group in the d-block, then you will get (n-1)d^5 ns^2.

[Justin Vayakone 1C]

In my solution manual, the answer to part c is ns^2 (n-1)d^3. That's the answer you said in your post right? ns^2 is the 2 valence electrons, and the (n-1)d^3 is the outermost d-orbital electrons.
