Tarix
Hennig Brand discovered phosphorus in 1669, in Hamburg, Germany, preparing it from urine.

In 1769, Johan Gottlieb Gahn and Carl Wilhelm Scheele showed that calcium phosphate is found in bones, and they obtained elemental phosphorus from bone ash.

Antoine Lavoisier recognized phosphorus as an element in 1777.

Applications
Many fertilisers contain a high proportion of phosphorus and are manufactured from concentrated phosphoric acids.

Phosphorus is used in the manufacture of safety matches, pyrotechnics and incendiary shells.

Phosphorus is also used in steel manufacture and in the production of phosphor bronze.
White phosphorus is highly toxic while red phosphorus is considered non-toxic
