much different physical properties. The 32P isotope is widely used in biology field as DNA or RNA probes.
» Common Phosphorus compounds:
• Diphosphorus Pentoxide, P2O5
• Phosphine, PH3
• Phosphorus Trichloride, PCl3
• Phosphoric Acid, H3PO4
• Phosphorous Acid, H3PO3
• Hypophosphorous Acid, H3PO2
Example Reactions:
• 3Rb + P = Rb3P
• P + 5HNO3 = 5NO2 + H2O + H3PO4
• 3Na + P = Na3P
