Phosphorus P
Where is phosphorus used--or where does it impact our everyday lives?
Used in safety flares
Phosporus is a dietary requirement
Phosphorus is present in calcium phosphate, Ca3(PO4)2, in bones.

Atomic number: 15 Atomic Mass: 30.97
Position on the periodic table: Group 15, on Period 3.
Melting point 44.2oC (111.38oF)
Boiling point 280.5oC (536.0 oF)
Reaction with O2: White phosphorus with oxygen P4 + 5O2 --> P4O10
No reaction with water (phosphorus is stored under water to eliminate air)
