The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
The oxidation number of P in H3PO3 is +3. Each hydrogen atom has an oxidation number of +1, and the overall molecule is neutral, meaning the sum of the oxidation numbers must be zero. Since oxygen usually has an oxidation number of -2, the oxidation number of P must be +3 to balance out the charges.
The oxidation number of Phosphorus (P) in H3P2O7 is +5. This can be determined by assigning hydrogen an oxidation number of +1 and oxygen an oxidation number of -2, then setting up an equation to solve for the unknown oxidation number of Phosphorus.
The oxidation number of P in P2O5 is +5. This is because oxygen typically has an oxidation number of -2, and there are 5 oxygen atoms in P2O5. The sum of the oxidation numbers in a neutral compound must equal zero, so the oxidation number of P is calculated as +5.
The oxidation number of P in H2PO2- is +1. This is because each hydrogen atom has an oxidation state of +1, and the overall charge of the ion is -1. Therefore, the oxidation number of phosphorus must be +1 to balance out the charge.
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.

The oxidation number of P in PCl3 is +3. This is because chlorine typically has an oxidation number of -1, and there are three chlorine atoms in PCl3, giving a total charge of -3. To balance this charge, the oxidation number of P must be +3.
The oxidation number of P in NaH2PO2 is +1. This is because Na and H have standard oxidation states of +1 and +1 respectively, and the overall molecule has to be neutral, so the oxidation number of P must be +1 to balance the charges.
The oxidation number of PH4 cannot be determined because phosphorus (P) does not have a fixed oxidation number in this compound.
In the phosphate ion (PO4^3-), the oxidation number of phosphorus (P) is +5. Each oxygen atom has an oxidation number of -2, resulting in a total charge of -3 for the phosphate ion.
The oxidation number of phosphorus (P) in PF3 is +3. This is because fluorine (F) has an oxidation number of -1, and the overall molecule PF3 has a total charge of 0.
The oxidation number of phosphorus (P) in H3PO5 is +5. Each hydrogen atom has an oxidation number of +1, and the oxygen atoms have oxidation numbers of -2. The sum of the oxidation numbers in a neutral compound must equal zero.
P= -4
