Question

Phosphorescence shown by P is due to​

Answer 1

Explanation:

The glow of phosphorus, however, though commonly called phosphorescence, is not actually an example of this pheno- menon. The glow is due to the oxidation of phosphorus, and is therefore an example of chemiluminescence. (see S.P., 1913, VIII, 54). lead, is added in the form of a salt of the metal during the fusion.

Answer 2

Answer:

phosphorescence is a process in which energy absorbed by a substance is released relatively slowly in the form of light. This is in some cases the mechanism used for "glow-in-the-dark" materials which are "charged" by exposure to light. Unlike the relatively swift reactions in fluorescence, such as those seen in a common fluorescent tube, phosphorescent materials "store" absorbed energy for a longer time, as the processes required to re-emit energy occur less often.
