In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
Minimum oxidation number: -1 Maximum oxidation number: 1 Min. common oxidation no.: 0 Max. common oxidation no.: 1 I got this of a really cool website that has alot of infromation and useful facts about each element and trust me you'll use it a lot in chemistry. www.chemicool.com
SO4^2- has a net negative 2 charge.each O = 2-S = 6+
0 in elemental form and 2+ in its compounds.
Oxidation states have changed.
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.
+4
This compound is not possible, but if it had been, the oxygen should have oxidation state of -4
For any element before reaction, its oxidation number is 0. Molecules made from the atoms of the same element have 0 oxidation state in each atom. Examples are gaseous hydrogen and liquid bromine.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
There are three elements, carbon, oxygen and hydrogen. Carbon's oxidation number is -4, each hydrogen is +1 and oxygen is +2.
In NaBrO3 the oxidation state of sodium (Na) is 1+, the oxidation state of bromine is 5+ and the oxidation state of each oxygen atom is 2-
It contains only two elements. N shows +1 and oxygen shows -2.

1. NH4Cl is an electrically neutral compound, so the sum of the oxidation states must be zero. 2. Nitrogen is a Group 5 element and is assigned an oxidation state of -3. 3. In its covalent compounds with nonmetals, hydrogen is assigned an oxidation state of +1. There are 4 hydrogen atoms, so contributes a charge of +4. 4. The oxidation state of a monatomic ion is the same as its charge. As a Group 7 element, chlorine is assigned an oxidation state of -1. 5. Adding up the oxidation states, -3, +4, -1, gives an overall charge of 0.
K[CuCl2]
Oxidation state is what determines the number of each atom. This is in the ionic formula.
