What is phosphorus electron affinity?

Phosphorus has a moderately high electron affinity, which means it has a tendency to attract an additional electron to form a negative ion. The electron affinity of phosphorus is -72 kJ/mol. This value indicates that phosphorus accepts an electron with relative ease but not as readily as some other elements such as chlorine or fluorine. The high electron affinity of phosphorus makes it useful in certain chemical reactions and in the production of electronic components. However, it also makes it potentially harmful if it is not handled properly.
