The four Oxygens stood at the corners of a tetrahedron, repelling each other equally. The molecule was symmetric, stable, and perfectly non-polar in its charge distribution, despite carrying a net negative charge.
"Since all four electron regions contain atoms," declared the Molecular Geometry, "your visible shape is... ." so4 2 electron geometry and molecular geometry
That’s when the arrived. The Electron Geometry is the ghostly, invisible blueprint of a molecule—it cares only about regions of negative charge . It doesn’t care if you are a lonely pair of electrons or a bonded pair; it just counts how many "clouds" are pushing against each other. The four Oxygens stood at the corners of
Sulfur looked at his six valence electrons and frowned. "I only have six to give, but I need to satisfy four guests." Sulfur looked at his six valence electrons and frowned
"Four regions," whispered the ghost of Electron Geometry. "That means I must arrange you in . 109.5 degrees apart. This is the most comfortable way for four clouds to sleep in the same bed."
