The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.

+3 for Cr and -2 for O
WHAT IS THE OXIDATION NUMBER OF OXYGEN AToms in o22?
The oxidation number of oxygen atoms in O2 is 0 because oxygen generally exhibits a zero oxidation state in elemental form.
What is the oxidation number of acetate?
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
What is the oxidation number of Mn in 2MnO2?
In MnO2, the oxidation number of oxygen is typically -2. Since there are two oxygen atoms in MnO2, the total oxidation number contributed by oxygen is -4. The overall charge of the compound is neutral, so the oxidation number of manganese (Mn) can be calculated by setting the total oxidation number equal to zero. Therefore, the oxidation number of Mn in 2MnO2 is +4.
What in the compound Fe2O3 irons oxidation number is plus 3 and oxidation number is?
In the compound Fe2O3, the iron atoms have an oxidation number of +3. This is because oxygen typically has an oxidation number of -2, so since there are three oxygen atoms in Fe2O3, the total negative charge from the oxygen atoms is -6. The two iron atoms must have a total charge of +6 to balance this, resulting in an oxidation number of +3 for each iron atom.
What is the oxidation number of Cr2O3?
+3 for Cr and -2 for O

What is the oxidation number for 6H?
The oxidation number for hydrogen (H) is typically +1. Therefore, the total oxidation number for 6 hydrogen atoms would be +6.
What is the oxidation number of each atoms Mn?
The oxidation number of manganese (Mn) can vary depending on the compound it is in. In MnO2, the oxidation number of Mn is +4, while in KMnO4, the oxidation number of Mn is +7.
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 oxidation number of nitrogen for N2O?
The oxidation number of nitrogen in N2O is +1. This is because oxygen is typically assigned an oxidation number of -2, so the two oxygen atoms in N2O contribute a total oxidation number of -4. Since the overall charge of the compound is 0, the two nitrogen atoms must have a total oxidation number of +4, making the oxidation number of each nitrogen atom +1.
What are the oxidation numbers of the elements in the Fe2O3?
study island answer is +3 -2
What is the oxidation number of carbon in sucrose?
The oxidation number of carbon in sucrose is +4. In sucrose (C12H22O11), the carbon atoms are bonded to oxygen atoms through double bonds, causing the oxidation state of carbon to be +4.
What is the oxidation number of H2CO2?
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
