-2 for Oxygen, +2 for Iodine
The oxidation number of iodine in Ca(IO)2 is +5. This is because the overall charge of the compound Ca(IO)2 is 0, and each oxygen atom has a charge of -2, so iodine must have a charge of +5 to balance the charges in the compound.
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.
Chlorine, bromine, and iodine can have both 1+ and 1- oxidation states. They most often occur in the 1- oxidation state, often in tho form , especially as the ions Cl-, Br-, and I- but can also achieve as 1+ oxidation state, particularly in the oxyanions ClO-, BrO-, IO- and the corresponding acids.
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.
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
The oxidation number of iodine in Ca(IO)2 is +5. This is because the overall charge of the compound Ca(IO)2 is 0, and each oxygen atom has a charge of -2, so iodine must have a charge of +5 to balance the charges in the compound.
