d5 and d10 e- exception

[Justin Bui 2L]

In lecture, we went over the first row of transition metals and at Chromium and Copper, there's the d5 and d10 exception. Do those exceptions work exactly the same for the elements in Chromium and Copper's respective groups as well?

[Adrian Franco 3H]

Yes, I believe so because in the HW, silver is in the same group as copper and its electron configuration is [Kr]4d^10 5s^1 instead of [Kr]4d^9 5s^2 due to certain elements being more stable with full orbitals rather than partially full orbitals. However, there are more exceptions/complications that we haven't learned about yet so I would just memorize Cu and Cr.

[Justin Chang 2K]

Yeah, all of the elements in those 2 groups have the same exception with the s and d shell, but for the purposes of this class, just memorize copper and chromium.

[Seth_Evasco1L]

All of the elements in the groups containing Copper have the same exception for their electron configuration. However, the only element to have a normal electron configuration in Chromium's group is Tungsten(W).

[Isabella Zizolfi 2F]

Yes, all the elements in group 11 and 6 are considered exceptions and so they act like Cr and Cu
