In a compound the sum of oxidation states of the elements contained is zero.
E1 + E2 + ... = 0
If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
It is determined from known oxidation states of other elements.
The unknown oxidation state of an element in a compound can be determined by using a set of rules based on the known oxidation states of other elements in the compound. First, assign oxidation states to all known elements according to standard rules, such as those for group elements and common ions. Then, apply the principle that the sum of oxidation states in a neutral compound must equal zero or match the charge of a polyatomic ion. By solving the resulting equation, the unknown oxidation state can be deduced.

In K2TaF7, the oxidation number of K is +1, Ta is +5, and F is -1. This is determined by assigning known oxidation numbers to the compounds (K is typically +1 and F is -1) and solving for the unknown ones (Ta).
The oxidation number of Mn in KMnO4 is +7. This can be determined by assigning the known oxidation numbers of potassium (+1) and oxygen (-2) and solving for the unknown oxidation number of manganese.
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 state of P in PO33- is +3. This can be determined by assigning -2 to each oxygen atom and solving for the unknown oxidation state of phosphorus to ensure the overall charge of the ion is balanced.
The oxidation number of Fe in Fe2S3 is +3. This can be determined by setting up an equation where the total oxidation number of the compound is equal to zero, and solving for the unknown oxidation number of Fe.
The oxidation number of carbon in Fe(CN)6^3- is -3. To find this, you can set up the equation where the total charge of the complex ion equals the sum of the oxidation numbers of each element in the ion and solve for the unknown oxidation number.
To calculate the oxidation number of an element in a compound, follow these steps: 1. Assign known oxidation numbers, such as +1 for hydrogen and -2 for oxygen. 2. Use algebraic rules to solve for the unknown oxidation number based on the compound's overall charge or known oxidation numbers of other elements. 3. Remember that the sum of oxidation numbers in a compound equals zero, or equals the compound's net charge if it is an ion.
The unknown element is neither a battery nor a resistor.
