In the question, "Electron Configuration of Tellurium", there is mention of the 'follow yellow brick road' method of finding electron configuration.
What I'd learned in the past was to find the nearest noble gas (in the row above the element of interest) and count from there.
I searched in Google for this method and see that it appears to also called the Aufbau principle & diagonal method. However I'm not getting a good grasp on how it works.
Could someone explain this method to me?
Also, would this method work for something with a weird electron configuration, like copper?
