Oxidation Numbers

The maximum oxidation number is the highest possible oxidation state that an element can exhibit in a chemical compound. It is typically reached when the element gains or loses electrons to achieve a stable configuration.

The oxidation number of the central atom Al in AlF6^3- is +3. This is because each F atom contributes a -1 charge, and the overall charge of the complex ion is -3, so the Al atom must have a +3 oxidation state to balance it out.

The oxidation number of N in NO is +2. Oxygen typically has an oxidation number of -2, so the oxidation number of nitrogen can be calculated as follows: x + (-2) = 0, where x is the oxidation number of N. Solving for x gives an oxidation number of +2 for N.

The oxidation number of Pt in PtCl6 is +4. Each Cl has an oxidation number of -1, and since the overall charge of the complex ion is 0, the oxidation number of Pt must be +4 to balance the charges.

The Iron has a 3+ charge, but the Cl each have a -1 charge so they balance out to an even charge of +/- 0

The oxidation number of sulfur can vary depending on the compound it is in. In most cases, sulfur has an oxidation number of -2, as seen in hydrogen sulfide (H2S) or sulfur dioxide (SO2). However, in some compounds such as sulfuric acid (H2SO4), sulfur can have an oxidation number of +6.

Copper iodide has a chemical formula of CuI. In this compound, the oxidation number of copper is +1.

The oxidation number of copper in CuI is +1. This is because iodine has an oxidation number of -1, and in ionic compounds like CuI, the overall charge must be neutral. Since there is only one iodine atom with a charge of -1, the copper atom must have an oxidation number of +1 to balance the charges.

The oxidation number of carbon (C) in Al4C3 is -4. This is because aluminum (Al) has an oxidation number of +3 and there are 4 aluminum atoms for a total oxidation number of +12. This must be balanced by the oxidation numbers of the carbon atoms, which must be -4 in order for the compound to be neutral.

The oxidation number of bromine in KBr is -1. In ionic compounds, the oxidation number of the cation (K+) is always equal to its charge, which is +1. Therefore, the oxidation number of bromine must be -1 to balance the overall charge of the compound.

Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.

The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.

The oxidation number for boron in B2H6 is +3, and the oxidation number for hydrogen is -1. Each boron atom has an oxidation number of +3, and each hydrogen atom has an oxidation number of -1 in the B2H6 molecule.

Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.

In K2TaF7, the oxidation number of K is +1, Ta is +5, and F is -1. This is determined by assigning known oxidation numbers to the compounds (K is typically +1 and F is -1) and solving for the unknown ones (Ta).

The +2 oxidation state in carbon typically occurs when carbon forms four covalent bonds, as in compounds like carbon dioxide (CO2) or carbon monoxide (CO). In these compounds, carbon has achieved a full valence shell by accepting or sharing electrons, resulting in an oxidation state of +2.

Cobalt is a transition metal. Its oxidation states are 2 (3).

The oxidation number change for the iron atom in a reaction is from Fe^0 (elemental form) to Fe^2+ or Fe^3+ (ionic form). This represents an oxidation of the iron atom, as it loses electrons and increases its oxidation state.

0 in elemental form

+3 in most of its stable compounds

In Mn(CrO4)2 manganese has +4 oxidationnumber, the ioncharge of chromate ion (CrO42-) is -2.

The oxidation number of zinc in Zn^{2+} is +2 because zinc typically loses two electrons to attain a full outer electron shell in its compounds.

In ICl (iodine chloride), iodine has an oxidation number of +1 because chlorine typically has an oxidation number of -1.

The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.
