[correctanswer]

For the U atom (electron configuration[Rn]7s^2 5f^3 6d^1 and of the ion U^3+ [Rn]5f^3
a) the valence orbitals and the high quality valence electrons are listed, draw a grid diagram
b) a high-quality determinant of determinant functions that can be built provide for the mentioned configuration configuration
c) modern numerical values ​​of S, L. and is characterized by the ground state of the atom, symbolized by the appropriate atomic term Russell-Saunders (2S + 1)^[L]_J and its degree of degeneration;
d) degree of degeneration corresponding to the atomic term (2S + 1)^[L] (when the rule of magnetic shock in an atom). In the sources, the basic method of three comparisons is presented Hundy regulation.
