Since for the electron configiration of the d-bock periods you have to subtract -1, so why are those d-block periods not just depicted one row abowe in the periodic table of elements (then it would be easier to directly read instead of conducting this subtraction as exeption)?
That's a great question! I wasn't consulted in the layout of the periodic table, lol, but the elements are in order of increasing atomic number / increasing number of protons. If all the d-block periods were moved up one level, they would be out of order in terms of their atomic number. It's a lose-lose situation :)
