To draw the Lewis structure first, we will find out the total valence electrons.

Valence electron of Phosphorous=  

Valence electron of Flourine=  

Total Valence electron=    

In PFPhosphorous exhibits expanded octet. It has more than eight i.e ten valence electrons.

Phosphorous being the least electronegative will occupy the central position. All Fluorine atoms will be around Phosphorous.

Step-by-step explanation

Step 1.

Total Valence electron=
