tetrahedral molecule requires that four ` A tetrahedral molecule requires that four orbitals of the central atom must overlap with an orbital of an outer atom to form a ond bond. he central atom would use its s orbital ` The central atom would use its s orbital and its three p orbitals, but these orbitals would not yield the 109° bond angles bserved in the tetrahedral molecule observed in the tetrahedral molecule.

` Valence-bond theory assumes that covalent bonds form when orbitals on different atoms overlap or occupy the same region of space. ` A sigma ( σ ) bond is a covalent bond in which e highest electron density lies between the the highest electron density lies between the two atoms along the bond axis connecting them.
