[1] For elements past 120, the configurations should be taken as very tentative, and in some cases mixing of configurations is very important.[2]. 8. The periodic table shown above demonstrates how the configuration of each element was aligned so that the last orbital filled is the same except for the shell. Which of these has more number of unpaired electrons? As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule. For Fe to convert to Fe3+ it will have to lose 2 electrons from 4s orbital and 1 electron from 3d orbital. 3 4 5 Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table.
