Lewis dot structure of PF3 contains 1 lone pair on the central atom(phosphorous) and 3 lone pairs on each outer atom(fluorine).
The diagrams known as Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.
The trigonal pyramid is the form or molecular geometry of PF3. Since PF3's core region comprises four zones of electron density, its electron geometry is tetrahedral. One lone pair is present on the core atom (phosphorus) in the Lewis dot structure of PF3, and three are present on each outside atom (fluorine).
