e- configuration of Pd and Ni

Postby DTingey_1C » Mon Oct 28, 2019 8:04 pm

Why is the e- configuration of Ni: [Ar] 3d8 4s2 while Pd is: [Kr] 4d10? Why isn't Ni [Ar] 3d10 like Pd is?

And why is copper: [Ar] 3d10 4s1 instead of [Ar] 3d9 4s2?

There are several elements that are anomalies when it comes to electron configuration, such as Copper, Silver, Gold, Palladium, Chromium, and Molybdenum. These elements designate more electrons to their d-subshells from the s-subshells for more stability. Unfortunately, you just have to know which ones don't comply with the normal rules.
