The ground-state electron configuration of oxygen atom is to be written. Valence electrons and core electrons in nitrogen are to be stated. Concept introduction: The arrangement of electrons in atomic orbitals is called the atom’s ‘electron configuration’. The most stable electron configuration of an element is called the ‘ground state’ configuration. Valence electrons are the electrons occupying the highest energy shell, while core electrons are the electrons occupying the remaining lower energy shells of an atom.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
