What is the oxidation number of each ion in Sodium oxide?
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
Why hydrogen has -1 oxidation number?
The oxidation state of oxygen is not -2, it is 0 - because oxygen is an element. Oxide, however, has oxidation state of -2. This is because the anion is O2- and the oxidation state of ions is equal to the charge held by the ion. The exception for oxide is that the oxidation state is -1 in peroxides e.g. H2O2 (hydrogen peroxide)
What is the oxidation number for Hydronium?
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
What is the oxidation number of chlorite?
In the Chlorite ion (ClO2-) chlorine's oxidation state is 3+ while oxygen's oxidation state is 2-
What is oxidation of iron is commonly referred to as?
A measure of the degree of oxidation of an atom in a substance. It is defined as the charge an atom might be imagined to have when electrons are counted according to an agreed-upon set of rules: (1) the oxidation state of a free element (uncombined element) is zero; (2) for a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion; (3) hydrogen has an oxidation state of 1 and oxygen has an oxidation state of -2 when they are present in most compounds. (Exceptions to this are that hydrogen has an oxidation state of -1 in hydrides of active metals, e.g. LiH, and oxygen has an oxidation state of -1 in peroxides, e.g. H2O2); (4) the algebraic sum of oxidation states of all atoms in a neutral molecule must be zero, while in ions the algebraic sum of the oxidation states of the constituent atoms must be equal to the charge on the ion. For example, the oxidation states of sulfur in H2S, S8(elementary sulfur), SO2, SO3, and H2SO4 are, respectively: -2, 0, +4, +6 and +6. The higher the oxidation state of a given atom, the greater is its degree of oxidation; the lower the oxidation state, the greater is its degree of reduction.

What is the oxidation state of SO42?
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-

What is the oxidation number for Hydronium?
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
What is the formula for oxide ion?
O2- is the formula for oxide ion. The negative symbol indicates the presence of anions and 2 represents the oxidation state.
What is the oxidation number of chlorite?
In the Chlorite ion (ClO2-) chlorine's oxidation state is 3+ while oxygen's oxidation state is 2-
Is an oxyanion named based on the amount of a metal in the ion?
No, the name of an oxyanion is not based on the amount of a metal in the ion. The name of an oxyanion is determined by the oxidation state of the element and the number of oxygen atoms in the ion. The metal in the ion may play a role in determining the charge or oxidation state of the element, but it does not directly determine the name of the oxyanion.

How do you figure out the formula for chromium 4 oxide?
Balance the oxidation states on the atoms in the molecule. An oxide always contains oxygen in -2 oxidation state , in ionic compounds this is O2-. As the chromium is Cr(IV) in +4 oxidation state, ( shown as an ion Cr4+ ) you can balance the states or charges which ever way to get CrO2 (which you can write as Cr4+ (O2-)2 )
What is the oxidation number for ti in Ti02?
This compound is white in color. Ti shows +4 in this compound.
What is that oxidation number of oxygen?
Typically in compounds it is -2 (oxide ion) - other values include zero (in O2 and O3)
How is an oxyanion named?
it is named for the number of oxygen atoms in the ion and/or oxidation state of the atom to which the oxygen is bonded.
