+2
The oxidation number for oxygen in most compounds is -2.
neutral ****************** 2nd Opinion: The answer is -2.
the most common oxidation number for oxygen is -2.
The oxidation number of chlorine can vary depending on the compound it is in. It can have an oxidation number of -1 in most compounds, but it can also have positive oxidation numbers in compounds like ClO4- where it has an oxidation number of +7.
The oxidation number of oxygen is -2 in most of its compounds
The element which has the same oxidation number in all of its known compounds is fluorine. Fluorine always has an oxidation number of -1 in its compounds because it is the most electronegative element.
The oxidation number of tellurium can vary depending on the compound it is in. In most compounds, tellurium has an oxidation number of -2, but it can also exhibit oxidation states of +2, +4, +6, and +7 in certain compounds.
+3 in its compounds
+1 in its compounds
0 in the elemental form, +3 and +4 are more common in its compounds.
The oxidation number of nitrogen can vary depending on the compound it is in. In most cases, nitrogen has an oxidation number of -3 when it is in its elemental form or in compounds like ammonia (NH3). However, in compounds like nitrate (NO3-), nitrogen has an oxidation number of +5.
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
