When a magnetic field is applied, the conduction band splits apart into a spin-up and a spin-down band due to the difference in magnetic potential energy for spin-up and spin-down electrons. B e In the presence of a magnetic field, these domains line up so that charges are parallel throughout the entire compound. This situation usually only occurs in relatively narrow (d-)bands, which are poorly delocalized. Paramagnetic. a. D. Rb 98 Mo. E. Sn, An atom of which of the following elements has the largest atomic radius? The statement that "the lowest-energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by the Pauli principle in a particular set of degenerate orbitals" is known as? Since the last electrons reside in the d orbitals, this magnetism must be due to having unpaired d electrons. For temperatures over a few K, The second ionization energy needed to form As(I) to As(II) is 1798 KJ/mol. Li and N are paramagnetic.
