This is due to the presence of a nonbonding electron pair on the P Lewis structure generator creates chemical structure diagrams for compounds. It is influenced by the number of bonding pairs and lone pairs of electrons around the central atom. My textbook says this is due to the presence of lone pair of phosphorous in $\ce {PH3}$ in an s-orbital. The lone pair exerts stronger repulsion than 9 شوال 1440 بعد الهجرة This is because the lone pair on the phosphorus atom repels the bonding pairs, causing the hydrogen atoms to arrange themselves in a pyramidal shape around the phosphorus atom.
