  • 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. Tuesday, November 5, 13
  • 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"). Tuesday, November 5, 13
  • 7. History of Phosphorus • Phosphorus was the 13th element to be discovered. • For this reason, and also due to its use in explosives, poisons and nerve agents, it is sometimes referred to as "the Devil's element". • It was the first element to be discovered that was not known since ancient times. Tuesday, November 5, 13
  • 8. Uses of Phosphorus • Today, Phosphorus is used in matches as the special lighting strip and is also used in water softening. Tuesday, November 5, 13
  • 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.
