How does the oxidation number of a monatomic ion compare to its charge?

The oxidation number of a monatomic ion equals its charge. For example, the oxidation number of a sodium ion (Na+) is +1, which matches its charge of +1.


How to solve for the oxidation number of charge of a polyatomic ion?

To find the oxidation number or charge of a polyatomic ion, consider the known charges of the individual atoms within the ion. For example, in the sulfate ion (SO4)2-, oxygen typically has an oxidation number of -2, and sulfur would then have an oxidation number to balance the charge of the ion. The sum of the oxidation numbers of all the atoms in the ion should equal the overall charge of the ion.


What is a monatomic ion has an oxidation number?

A monatomic ion is an ion consisting of a single atom with a positive or negative charge. The oxidation number of a monatomic ion is equal to the charge of the ion.


What is the oxidation number of an ion?

The oxidation number of an ion is the charge of the ion, which is determined by the number of electrons gained or lost by the atom to achieve a stable electron configuration. Positive ions have oxidation numbers that equal their charge, while negative ions have oxidation numbers that are the negative of their charge.


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.

How is charge related to oxidation number?

Charge refers to the electrical charge of an ion, which is the number of valence electrons gained or lost by an atom. Oxidation number, on the other hand, is a hypothetical charge assigned to an atom in a compound based on a set of rules. The oxidation number can be used to determine the charge of an ion in a compound, but it does not always represent the true charge of the atom.


What is the oxidation number of a mercury I ion?

It is equal to the charge. So Oxidation number is +1


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 oxidation number would you find on a metal ion and a non - metal ion?

A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.


What is the oxidation number of any monoatomic ions?

The oxidation number of any monoatomic ion is equal to the charge of the ion. For example, the oxidation number of the sodium ion (Na+) is +1, and the oxidation number of the chloride ion (Cl-) is -1.
