Unformatted text preview: H H 1s in-phase overlap of two half-filled
hydrogen 1s orbitals H H σ bond of H2
bond Valence Bond Model
σ Bond: orbitals overlap along
Cross section of orbital perpendicular to
internuclear axis is a circle.
internuclear H H Valence Bond Model of H2 Figure 2.4(a) The 1s orbitals of two separated hydrogen
atoms are far apart. Essentially no interaction. Each
electron is associated with a single proton.
