Recall that hybridization describes the mixing of atomic orbitals to form new hybrid orbitals suitable for bonding.
Identify that sp3 hybridization means one s orbital and three p orbitals combine, resulting in four equivalent hybrid orbitals.
Understand that these four sp3 hybrid orbitals arrange themselves to minimize electron repulsion, which leads to a specific electron geometry.
Recognize that the arrangement minimizing repulsion for four electron groups is a tetrahedral geometry, with bond angles of approximately 109.5°.
Conclude that an atom with sp3 hybridization has a tetrahedral electron geometry.
