Phosphorus has valency 3.
The valence (or valency) of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.
In PH3, P is combined to 3 H atoms, so the valency of phosphorous is +3.

The number of valence electrons or the number of electrons in the outermost shell of phosphorus is 3. - Thus, one atom of phosphorus is capable of combining with three atoms of hydrogen in order to form phosphine (PH3). Therefore, the valency of phosphorus in PH3 is +3.
