Range of oxidation number of phosphorus in its compounds:

Phosphorus is an element that can exhibit a range of oxidation states in its compounds. The oxidation number of phosphorus can vary from -3 to +5, making it one of the elements with the widest range of oxidation states.

Explanation:

Lowest oxidation state:
- The lowest oxidation state of phosphorus is -3, which is observed in compounds such as phosphine (PH3) and diphosphine (P2H4). In these compounds, phosphorus is in the form of phosphide ions where it has gained three electrons.

Higher oxidation states:
- Phosphorus can also exhibit higher oxidation states such as +3, +4, and +5 in various compounds.
- In compounds like phosphorus trichloride (PCl3), phosphorus is in the +3 oxidation state where it has lost three electrons.
- In compounds like phosphorus pentoxide (P2O5), phosphorus is in the +5 oxidation state where it has lost five electrons.

Conclusion:

Phosphorus shows a wide range of oxidation states in its compounds, from -3 to +5. This versatility in oxidation states allows phosphorus to form a variety of compounds with different properties and applications in various fields.
