There are a total of 26 valence electrons in the PF3 Lewis structure. The steric number of a single phosphorus trifluoride (PF3) molecule is four because it has three bonds (between the elements phosphorus and fluorine) and one empty pair of electrons.
The colorless and odorless gas phosphorus trifluoride (PF3) is poisonous in a manner similar to that of carbon monoxide. It spreads throughout the body by attaching to the iron in hemoglobin and preventing the blood from receiving oxygen. In a chemical process, PF3 acts as a nucleophile by donating two electrons. Hybridization, Molecular Geometry, and PF3 Lewis Structure.The number of valence electrons of an atom, which easily interact with the valence electrons of another atom to create a bond, is depicted in a Lewis diagram.
