Floating Spherical Gaussian Orbital Model of Molecular Structure. VIII Second-Row Atom Hydrides

Abstract

The FSGO model is applied to the second-row hydrides: NaH, MgH+, AlH, SiH4, PH3, H2S, and HCl. The trends in the bond lengths and electronegativities are correctly predicted. The bond lengths are predicted quantitatively with an average deviation of 3%. The calculated bond angle in PH3 is 90.9° compared with the experimental value of 93.2°, while for H2S the values are 87.7° compared with 92.2°.
