Effectiveness or effectivity is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression.
how to calculate the effective nuclear charge of transition metals using Zeff=Z-S? How does having a half-filled 4s1 orbital effect S?
I am guessing something with a half-filled 4s orbital such as Chromium will not be the simple Zeff=24-18. I guess the 4s1 configuration can't be ignored. I don't...
