Lewis diagram is a pictorial presentation of the number of valence electrons present in an atom, which readily reacts with the valence electrons of another atom to form a bond. PF3 does obey the octet rule. It binds to the iron present in the blood hemoglobin to spread throughout the body and prevents the blood from absorbing the oxygen. Here, the number eight has been selected as per the octet rule. 1,2 1,3 3,3 12,2 3,1 Posted by MakeTheBrainHappy on April 26, 2020. As the lone pair repulsion is stronger than the bond pair or bond pair-lone pair repulsion, it reduces the bond angle. Moreover, this further can be confirmed through the hybridization which says a single PF3 molecule shows 75% characteristics of p orbital. This angle makes the structure bent where the ideal bond angle for the bent, trigonal pyramidal structure is 109.5°. The electrons present in the outermost shell of an atom are called valence electrons. If we wanted, we could check the formal charges and you'd see that those work out. Phosphorus pentafluoride is a trigonal bipyramidal molecule. As a single phosphorus trifluoride (PF3) molecule has three bonds (between phosphorus and fluorine) and one lone pair of electrons, the steric number is four. To figure out the hybridization of the central atom, it is essential to determine the steric number in the phosphorus trifluoride (PF3) molecule. PF3 is a nucleophile where it donates a pair of electrons during a chemical reaction. Its main use is as a ligand in metal complexes.As a ligand, it parallels carbon monoxide in metal carbonyls, and indeed its toxicity is due to its binding with the iron in blood hemoglobin in a similar way to carbon monoxide. PF3 is a tetra-atomic molecule where phosphorus donates three valence electrons, and three fluorine atoms accept one electron each to undergo a bond formation and reach a stable condition.

Moreover, the line represents the formation of a bond between the valence electrons of the two atoms. This repulsion distorts the whole structure where the effect increases to many folds because of the smaller size of fluorine and shorter atomic radius distance. Dispersion forces act between all molecules. One sp3 hybrid orbital accommodates the lone pair of the electrons of the phosphorus. Whereas, on the other hand, the atomic number of fluorine is nine which makes its electronic configuration 1s2 2s2 2p5, having a scarcity of only one valence electron.
