Homework 2.55 part c

Postby NatalieSDis1A » Mon Apr 30, 2018 3:49 pm

2.55 Give the notation for the valence-shell configuration (including the outermost d electrons) of (a) the alkali metals; (b) Group 15 elements; (c) Group 5 transition metals; (d) "coinage" metals (Cu, Ag, Au).

Hello, I got parts a,b, and d of this problem correct. However the answer to part c does not match my intuition. I thought the answer would be (n-1)d3ns2. The answer from the back of the book is (n-1)d5ns2. Why does the correct answer have 5 electrons in the d orbital instead of 3?

Hi Natalie,
2.55(c) actually has a typo, as stated in Dr. Lavelle's correction to the textbook problems the correct answer is actually (n-1) d^3 ns^2. You were right!

Thank you! I didn’t know such a thing existed

Where do you find the corrections to the textbook problems? I only see the solution manual corrections.
