Condensed ground-state configuration

A condensed ground state configuration for sodium can be written using [Ne] to represent the first 10 electrons of sodium that have the identical configuration as neon. 

Use the aufbau principle to write the condensed ground state electron configurations for nitrogen, phosphorus, and arsenic. 

Write the condensed ground state electronic configuration for iodine, manganese, and barium. 

Even though there are several exceptions, in general, the condensed ground-state electron configuration for the elements in each r/-block series is... 

Problems with colored numbers are answered in Appendix E. Sections match the text and provide the numbers of relevant sarnie problems. Bracketed problems are grouped in pairs (indicated ly a short rule) that cover the same concept. Comprehensive Problems are based on material from any section or previous chapter. Note In these problems, the term electron configuration refers to the condensed, ground-state electron configuration. 

Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic ... 

Even though there are several exceptions, in general, the condensed ground-state electron configuration for the elements in each condensed configuration includes the / sublevel ... 

The correspondence diagram in Fig. 9.4 can be applied to either the selective production of HDH2(i4i) or H2(Bi) or to the simultaneous formation of both. The ground-state configuration of the valence electrons of N2 (Section 3.2.2), desymmetrized from Dqo/i to with the aid of Table 3.2, can be condensed to ... 

Draw a partial (valence-level) orbital diagram, and write the condensed ground-state electron configuration for each ... 

Note In these problems, the term electron configuration refers to the condensed, ground-state electron configuration. 

Associated with their strong tendency to condense occupancy in the lowest few orbitals, the NAOs on each center A typically separate into two distinct sets (i) the high-occupancy natural minimal basis (NMB) set, equal in number and type to the nominal minimal basis of occupied Hartree-Fock AOs in the atomic ground-state configuration, and (ii) the low-occupancy natural Rydberg basis (NRB) set, corresponding... 

Inspection of Table 2 reveals that all those molecules that suffer a molecular-symmetry reduction in the ground state possess (E2 — E1) values considerably larger than the critical value, so that they should have a fully-symmetrical nuclear configuration in their first excited states. On the other hand, there are cases where a molecule has an ( , — Eg) value significantly higher than the critical value, but has a relatively smaller (Ej— i) value. The ( 2 i) value of the pentalene dianion (I ) is of the same order of magnitude as the critical value and those for the peri-condensed nonalternant hydrocarbon, XVII, the fulvalenes, XXI, XXII and XXIII, and the dianions, IVand VII are significantly smaller than the critical value ( 0.6eV).
