The Chemistry of Nonmetals - Purdue University
Calcium (EN = 1.00), on the other hand, is significantly less electronegative than phosphorus (EN = 2.19). When these elements react, the electrons are drawn toward the more electronegative phosphorus atoms. As a result, calcium is oxidized and phosphorus is reduced. The behavior of the nonmetals can be summarized as follows. 1.
