Oxidation state of Oxygen in:
Peroxides is -1
Superoxides is - 1/2
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.
As with any element, the oxidation state of oxygen is 0 in its elemental form.
When alkali metals are heated, they react with oxygen to form various oxy compounds, primarily metal oxides (e.g., sodium oxide, Na2O, and potassium oxide, K2O). In some cases, they can also form peroxides (e.g., sodium peroxide, Na2O2) and superoxides (e.g., potassium superoxide, KO2), depending on the specific metal and the reaction conditions. These compounds exhibit distinct properties and reactivity based on the oxidation state of the metal and the type of oxygen species involved.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
The oxidation state of oxygen in O2PtF6 is zero. In a molecule of O2, the oxidation state of each oxygen atom is -2. Additionally, the compound PtF6 has a +6 charge, so the two oxygen atoms in O2PtF6 must have an oxidation state of zero to balance the overall charge of the compound.
In most compounds oxygen will have an oxidation state of -2. The only exceptions are peroxides (-1), superoxides (-1/2), and compounds in which oxygen bonds with fluorine (+1 or +2).
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
In terms of ionic compounds an oxide contain the oxide ion (O2-) Which is a single oxygen atom with a 2- charge. A peroxide contains the peroxide ion (O22-) which is a particle of two oxygen atoms bonded together and has a 2- charge. Unlike most normal oxides, peroxides tend to be oxidizers or at the very least, unstable. A superoxide contains the superoxide ion (O2-) which consists of two oxygen atoms bonded together and has a 1- charge. This ion is even more strongly oxidizing than the peroxide ion. In covalent compounds oxides are substances that contain oxygen in the 2- oxidation state and not bonded ot other oxygen atoms. Peroxide contain a peroxide group (O2) in which each oxygen atom is bonded to the other oxygen an to another atom, typically carbon or hydrogen. IN this case oxygen is in the 1- oxidation state.
The oxidation number of an element depend on another element it react with to form a compound e.g manganese(iv)oxide mno4 the oxidation number of oxygen there is four while the oxidation number of manganse is 7 in most radox reaction the oxidation number of oxygen is usually 4 when writing the full equation
O standing for oxygen can have multiple oxidation numbers depending on what it is bonded to, in most cases it has a negative 2 oxidation number but in certain cases like peroxides it can have a negative 1 oxidation state.
The oxidation number of chlorine is -1 in most states but it can be altered in certain compounds.
-1. In simple inorganic compounds other than peroxides and superoxides, oxygen almost always has an oxidation number of -2, but since calcium cations always have an oxidation number of +2, in this compound, the two oxygen atoms must have only -1 charge each. This compound is calcium peroxide, one of the exceptions noted above.
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.
Oxidation is one part of a redox reaction, where redox stands for reduction-oxidation. Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion. It need not involve any oxygen and the question is too underspecified to have a sensible answer.
Oxygen usually has an oxidation state of -2.
The oxidation state of oxygen in the compound is -2.
The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
