What is true about the sum of all oxidation numbers?
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
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.
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 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.
What must the sum of the oxidation number be equal to?
It must be equal to the charge on the compound/ion

Sum of oxidation numbers charge in a compound?
The sum of oxidation numbers in a neutral compound is always zero, as the charges balance out. In polyatomic ions, the sum of oxidation numbers equals the charge of the ion. When determining oxidation numbers, rules such as assigning elements in their elemental state an oxidation number of zero and hydrogen an oxidation number of +1 are typically followed.
What is the oxidation number of CO3?
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
What are the rules for oxidation numbers?
The oxidation number of an atom in its elemental form is 0. In a compound, the sum of oxidation numbers must equal the overall charge of the compound. In a polyatomic ion, the sum of oxidation numbers must equal the charge of the ion. Some elements have fixed oxidation numbers (e.g., alkali metals +1, alkaline earth metals +2).
What is the sum of the oxidation numbers in a molecule?
The sum of oxidation numbers in an uncharged molecule will be 0.For example, H2O has O2- and 2H+.1(-2) + 2(+1)=0The sum of oxidation numbers in a charged species will equal the charge.For example, HCO3- has H+, C4+, and 3O2-.1(+1) + 1(+4) + 3(-2) = -1
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.
How is oxidation number determined for ionic compounds?
In ionic compounds, the oxidation number is determined by the charge associated with each ion. For cations, the oxidation number is the same as the charge on the ion. For anions, the oxidation number is the negative of the charge on the ion. The sum of the oxidation numbers in an ionic compound must be zero.
What is the oxidation numbers in PO34?
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
