Fluorine, chlorine, bromine and iodine The chemistry of fluorine, chlorine, bromine and iodine is probably better understood than that of any other group of elements except the alkali metals. This is partly because much of the chemistry of the halogens is that of singly bonded atoms or singly charged anions, and partly because of the wealth of structural and physicochemical data available for most of their compounds. The fundamental principles of inorganic chemistry are often illustrated by discussing properties of the halogens and halide compounds, and topics already discussed include: . electron affinities of the halogens (Section 1.10); . . . . . . . . . . . . valence bond theory for F2 (Section 1.12); molecular orbital theory for F2 (Section 1.13); electronegativities of the halogens (Section 1.15); dipole moments of hydrogen halides (Section 1.16); bonding in HF by molecular orbital theory (Section 1.17); VSEPR model (which works well for many halide compounds, Section 1.19); application of the packing-of-spheres model, solid state structure of F2 (Section 5.3); ionic radii (Section 5.10); ionic lattices: NaCl, CsCl, CaF2 , antifluorite, CdI2 (Section 5.11); lattice energies: comparisons of experimental and calculated values for metal halides (Section 5.15); estimation of fluoride ion affinities (Section 5.16); estimation of standard enthalpies of .
