I am confused as to how we should order the electron configurations. I recall the correct order being like 4s2 then 3d10. However, in the textbook and midterm solutions it shows them being 3s2 3p6 3d10 then 4s2 4p6 etc. Which is right??
4s would come after 3d!! In high school most of us learned to put the 4s before the 3d since they are in that order on the periodic table, but energy level wise the 4s would come after 3d. To put it simply, whenever you're doing electron configuration, put them in numerical order.
