Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Phosphine (IUPAC name: phosphane) is the compound with the chemical formula PH3. It is a colorless, flammable, toxic gas and is classed as a pnictogen hydride.

Explanation:

Drawing the Lewis Structure for PH

The PH3 Lewis structure has 8 valence electrons. Remember that hydrogen (H) only needs two valence electrons to have a full outershell. The Lewis structure for PH3 is similar the the structure for NH3 since both P and N are in the same group on the Periodic table.

you need to have a picture of the atom that way we can answer it
