Ch. 8 (#2)

• The overlap of two s orbitals, the overlap of an s orbital and a p orbital, and the end-to-end overlap of two p orbitals all produce

  Sigma bonds
• Describes a covalent bond as the overlap of half-filled atomic orbitals that yield a pair of electrons shared between the two bonded atoms

  Valence bond theory
• A type of covalent bond that results from side-by-side overlap of two p orbitals

  Pi bond
• A plane with no probability of finding an electron

  Node
• The process of combining the wave functions for atomic orbitals is called

  Hybridization
• T/F: Hybrid orbitals do not exist in isolated atoms. They are formed only in covalently bonded atoms.

  True
• Hybrid orbitals have shapes and ___ that are very different from those of The atomic orbitals in isolated atoms

  Orientations
• A set of ___ ___ is generated by combining atomic orbitals. The number of hybrid orbitals in a set is equal to the number of atomic orbitals that were combined to produce the set

  Hybrid orbitals
• All orbitals in a set of hybrid orbitals are equivalent in ___ & ___.

  Shape and energy
• The type of hybrid orbitals formed in a bonded atom depends on its ___ - ___ ___ as predicted by the VSEPR theory

  Electron-pair geometry
• T/F: Hybrid orbitals overlap to form sigma bonds. Unhybridized orbitals overlap to form pi bonds.
