Electronic Configurations of Atoms and Mononuclear Ions Atomic Orbital Quantum Numbers Which of the following statements about electronic configurations of atoms and mononuclear ions, and atomic orbital quantum numbers, are true or false. true Fe2+ has the same electronic configuration as Co3+. alse The valence electronic configuration of bromine is 4s24p5. true The secondary (angular momentum) quantum number is always an odd number. true The value of I is always equal to n minus one. alseLa3+ has the same electronic configuration as Iodine. For cations of the first transition series the 3d orbitals are significantly lower in energy than the 4s. Whereas in the neutral atoms the 4s and 3d orbitals are close in energy.
