What is the oxidation state of persulfate anion?
Persulphate = S2O82- O.S. of S = +7 O.S. of O = -2
How does oxidation numbers determine the number of atoms?
Oxidation numbers indicate the charge of an atom in a compound. By comparing the oxidation numbers of different atoms in a compound and knowing their charges, you can determine the number of atoms involved in the reaction or compound. These numbers help balance chemical equations and determine the stoichiometry of a reaction.
Is covalent molecules have oxidation number?
No, covalent molecules do not have oxidation numbers. Oxidation numbers are assigned to individual atoms in ionic compounds based on their electronegativity and sharing of electrons. In covalent molecules, electrons are shared between atoms, making it difficult to assign oxidation numbers.
In a polyatomic ion the algebraic sum of the oxidation numbers of all atoms is equal to?
The algebraic sum of the oxidation numbers of all atoms in a polyatomic ion is equal to the overall charge of the ion.
What is the sum of the oxidation numbers for P2O5?
The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.

What are the oxidation numbers in KCl?
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.
What is the sum of the oxidation numbers in a neutral compound?
In a neutral compound, the sum of the oxidation numbers of the atoms in the compound is zero.
In a polyatomic ion the algebraic sum of the oxidation numbers of all atoms is equal to?
The algebraic sum of the oxidation numbers of all atoms in a polyatomic ion is equal to the overall charge of the ion.
What is the sum of the oxidation numbers for P2O5?

What are the rules to follow in assigning an oxidation number?
In a neutral compound, the sum of oxidation numbers of all atoms will be zero. In a polyatomic ion, the sum of oxidation numbers of all atoms will be equal to the charge of the ion. The oxidation number of an element in its elemental form is zero. Fluorine always has an oxidation number of -1 in compounds. Oxygen usually has an oxidation number of -2 in compounds.
What is the sum of the oxidation numbers in the phosphate ion?
The sum of the oxidation numbers in the phosphate ion (PO4^3-) is -3. Each oxygen atom has an oxidation number of -2, totaling -8. The oxidation number for phosphorus is +5 to offset the oxygen atoms and give a total charge of -3 for the ion.
In a polyatomic ion the algebraic sum of all the oxidation numbers of all atoms equal to?
the charge on that ion
What is the sum of all oxidation numbers in any compound?
The sum of all oxidation numbers in any compound is zero. This is because atoms in a compound are electrically neutral, and the oxidation numbers reflect the charge of the atoms when they gain or lose electrons.
Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
