Webb(e) twice as many electrons in its second shell as in its first shell? Solution: a) Neon has two shells which are completely filled. b) Magnesium has electronic configuration 2, 8, 2. c) Silicon has a total of three shells, with four electrons in its valence shell. d) Boron has a total of two shells, with three electrons in its valence shell WebbIt is shown that the major features of complete valence-shell ionization spectra can be predicted using direct diagonalization. A comparison is made with the 2p-h Tamm-Dancoff approximation, and results are presented for the ethylene molecule using a h 3 manifold containing over 23000 operators.
