Cu and Cr

Postby Rohan Kubba Dis 4B » Sat Nov 02, 2019 11:12 am

Obviously Copper and Chromium have special electron configurations to maintain stability (3d10 4s1 and 3d5 4s1), however, does this trend continue to the corresponding elements in each group (Molybdenum for Chromium and Silver for Copper)?

Yes, this trend continues for elements below copper and chromium, because a half-filled d orbital is more energetically stable.

Yes! Because all of the elements in that group have the same valence electron orbital formation; therefore, all of them will exhibit similar characteristics when it comes to arranging valence electrons.

Yes this trend apples to all 4 of the "coinage" metals

Yes the trend continues! Hope this helps.

yes, this exception to the normal electron configuration will continue for the elements down the group because they will have the same valence electron configuration just different orbital levels.

It was mentioned during one of the chemistry reviews that these configuration exceptions are favorable due to the symmetry that is created within them.

So this means that this trend would also apply to silver as it applies to copper?

Yes because the electrons are more stable in that state so the trend still applies

Yes this trend continues because it provides symmetry and the electrons would rather want to go into an orbital by itself rather than be next to another paired because they of e-e repulsion. Therefore, there is more stability and symmetry in half filled and full filled shells.

Yes. Since all the elements in that column have the same number of valance electrons they will follow the same exception.

Yes, the trend would continue!
