Phosphorus has valence 3 or 5 in compounds, which have many uses in industry. Phosphine (PH3)is a chemical raw material and a doping agent (deliberately added impurity )for solid-state electronics components. Organic phosphorus compounds are used as plasticizers, gasoline additives, insecticides (e.g., parathion), and nerve gases.

磷在化合物中的原子价为3或5,工业用途很多。磷化氢(PH3)是一种化学原料,也是固态电子化学物的掺杂剂。有机磷化学物用作可塑剂、汽油填加剂、杀虫剂(如巴拉松)和神经毒气。
