1E25c

Postby JChen_2I » Mon Oct 21, 2019 4:59 pm

Give the notation for the valence-shell configuration (including the outermost d-electrons) of Group 5 transition metals

Could someone please explain how the answer to this is (n-1)d^5ns^2?
Thank you!

Not sure if you made a typo or not, but the answer to 1E25c is (n-1)d^3ns^2. This is because the G5 transition metals are located in the 3rd section in the d block, making it d^3. And because it is to the right of G1 and G2, it also includes s^2. The principal quantum number n is an indicator of the energy level for the s subshell, but it needs to be subtracted by 1 in order to get the energy level for the d subshell
