Phosphorus is therefore oxidized in this reaction, and oxygen is reduced. 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 Amazing Uses of Lead That Make it a Versatile Metal

Lead is a soft, malleable metal included in the group of heavy metals. It has a lustrous silver-blue appearance when freshly cut, but darkens to a dull grayish color when exposed to moist air. This occurs due to the immediate formation of an oxide film that protects the metal from further oxidation or corrosion.
