5. Properties of
Phosphorus
•
•
Phosphorus is a Non-Metal.
•
It is widely distributed in many
minerals, mainly phosphates.
Elemental phosphorus exists in two
major forms—white phosphorus and
red phosphorus—but due to its high
reactivity, phosphorus is never found
as a free element on Earth.

6. Discovery of
Phosphorus
•
The discovery of phosphorus is credited to the German
alchemist Hennig Brand in 1669.
•
Brand experimented with urine, which contains
considerable quantities of dissolved phosphates from
normal metabolism. Working in Hamburg, Brand
attempted to create the fabled philosopher's stone
through the distillation of some salts by evaporating
urine, and in the process produced a white material that
glowed in the dark and burned brilliantly. It was named
phosphorus mirabilis ("miraculous bearer of light").

that was not known since ancient times.

9. Phosphorus in our
Bodies
•
Phosphorus is an important constituent in
every body tissue. The total amount
constitutes about one per cent of the body
weight. The amount of phosphorus in the
body is exceeded only by calcium.
•
It combines with calcium to form a relatively
insoluble compound calcium phosphate,
which gives strength and rigidity to bones
and teeth.
