[48], Using a ligand called Eind (1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl) germanium is able to form a double bond with oxygen (germanone). Find out the number of valence electrons further needed of a single PF3 molecule to stabilize itself. [77] High-brightness LEDs, used for automobile headlights and to backlight LCD screens, are also an important application. The Oxygen and Carbon have an octet in their outer shell and the Hydrogen has filled valence shells. Step 1: Draw the Lewis structure, Step 2: Draw the 3D molecular structure w/ VSEPR rules, Step 3: Use symmetry to determine if the molecule is polar or non-polar.
