Ground state configuration of elements

The assignment of electrons to the various atomic orbitals, as discussed in Chapter 8, concerned the electron distribution in the ground state (the state having the lowest energy) of an isolated free atom. From the following ground-state configurations of elements in the second period. 

Particular attention has been paid to element 114 because the nucleus with Z = 114 and W = 184 is magic in both the number of protons and neutrons and has a predicted lifetime of anywhere between minutes to years. The ground state configuration of element 114 is predicted to be 7s 7p 2 small MCDF calculation (in detail 98.9%...
