+5 oxidation state
Phosphorous, or P, has a zero oxidation number in the element. Common oxidation numbers are:- It has a -3 in phosphides, where it forms the P3- ion It has a +3 in oxidation number in for example P4O6, and PCl3 It has a +5 oxidation number in for example P4O10 and PCl5
The answer is +7 because the oxygen has a charge of -8 and the charge on the whole compound is -1 therefore the charge on Cl must be +7.
+3
Phosphorus in PCl5 Nitrogen in Nitrate (NO3-) ion
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
The oxidation state of phosphorous in PCl5 is +5.The valence shell has 5 electrons.It therefore cannot increase its oxidation state more than 5.Therefore PCl5 cannot act as a reducing agent as it cannot donate electrons.The oxidation state can be decreased to +3 by gaining electrons. There for PCl5 can act as a oxidizing agent.A example is given below along with the change in oxidation states of phosphorous.
The oxidation no of phosphorus is +3 and that of chlorine is -1.

Mg = +2 oxidation state P = +5 oxidation state O = -2 oxidation state
O = -2 oxidation state P = +5 oxidation state
The answer is +7 because the oxygen has a charge of -8 and the charge on the whole compound is -1 therefore the charge on Cl must be +7.
+3
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
