A chemical bond formation is attributed to the tendency of a system to attain stability. It was observed that the inertness of noble gases was because of their fully filled outermost orbitals. Hence, it was postulated that the elements having incomplete outermost shells are unstable (reactive). Apr 11, 2016 · a) The H2S bond angle will be about 109.5 degrees since it has a Bent molecular geometry. b) The shape of BCl3 is trigonal planar, which means that the bond angles are all 120 degrees . The molecular geometry can be different as a solid, in solution, and as a gas. The position of each atom is determined by the nature of the chemical bonds by which it is connected to its neighboring atoms. The molecular geometry can be described by the positions of these atoms in space, evoking bond lengths of two joined atoms, bond angles of ...Section 6.5 – Molecular Geometry The properties of molecules depend on the bonding and the molecular geometry, the 3-dimensional arrangement of the atoms in space.
