Sulfur is the central atom with 3 oxygens bonded to it (1 double bond and 2 single bonds). When counting electrons, one electron pair remains. Because sulfur can have an expanded octet, it takes the electron pair giving it an AX3E or trigonal pyramidal geometry.
Hi! The molecular shape of a sulfite ion is trigonal pyramidal because it has 4 regions of electron density (3 bonding pairs and 1 lone pair) and follows the AX3E VSEPR notation. The four pairs are arranged tetrahedrally, but because only atom positions are used to name the shape of a molecule, the molecular shape is trigonal pyramidal. Hope this helps!
