I3 - Molecular Geometry, Bond Angles & Electron Geometry
WebWe know that phosphorus is the core atom, with two electron pairs bound (three P-F) and one lone pair of electrons. The general molecular geometry formula for PF3 is AX3N1. According to the VSEPR theory, if the PF3 molecule ion has an AX3N1 generic formula, the molecular geometry and electron geometry will both be trigonal pyramidal forms. WebLooking at the formal charges on the atoms, each oxygen has a charge of -2. With the added electron, the iodine has a formal charge of +5. This leaves 2 electrons in the valance shell for the lone pair. So there are 4 items (3 oxygens and a lone pair) to place around the iodine atom, giving it a tetrahedral shape. WebLooking at the formal charges on the atoms, each oxygen has a charge of -2. With the added electron, the iodine has a formal charge of +5. This leaves 2 electrons in the … black hound polo
