What is the rule for electron configuration, i do not understand it. Also isn’t the maximum number of electrons in shell 4, 32?
In: Chemistry
Because if you look _very_ closely at what the actual energy levels are in those 4 and 5 shells, then slots 19-22 in the 4 shell (the first four f slots, I believe) are all actually slightly higher than slots 1-4 in shell 5 (the two s slots and the first two p slots).
So those 4 electrons go into the lowest remaining 4 slots, which are all in shell 5.
–Dave, if you think that’s weird, don’t look closely at the lanthanides or actinides
