| 单词 | oxidation number |
| 例句 | To clarify the similarity of this reaction to the previous one and permit an unambiguous definition of redox reactions, a property called oxidation number has been defined. Chemistry 2019-02-14T00:00:00Z For complexes of the same metal ion with no change in oxidation number, the stability increases as the number of electrons in the t2g orbitals increases. Chemistry 2019-02-14T00:00:00Z Recall that oxygen is generally assigned a –2 oxidation number unless it is elemental or attached to a fluorine. Chemistry 2019-02-14T00:00:00Z Since carbon does not have a specific rule, its oxidation number is determined algebraically by factoring the atoms it is attached to and the overall charge of the molecule or ion. Chemistry 2019-02-14T00:00:00Z In general, a carbon atom attached to an oxygen atom will have a more positive oxidation number and a carbon atom attached to a hydrogen atom will have a more negative oxidation number. Chemistry 2019-02-14T00:00:00Z The oxidation number of an element in a compound is essentially an assessment of how the electronic environment of its atoms is different in comparison to atoms of the pure element. Chemistry 2019-02-14T00:00:00Z Draw the Lewis structure and determine the oxidation number and hybridization for each carbon atom in the molecule. Chemistry 2019-02-14T00:00:00Z Hydrogen is generally assigned an oxidation number of +1 unless it is attached to a metal. Chemistry 2019-02-14T00:00:00Z Redox reactions involve a change in oxidation number for one or more reactant elements. Chemistry 2019-02-14T00:00:00Z For an atom in a compound, the oxidation number is equal to the charge the atom would have in the compound if the compound were ionic. Chemistry 2019-02-14T00:00:00Z By this description, the oxidation number of an atom in an element is equal to zero. Chemistry 2019-02-14T00:00:00Z Identify the oxidizing agent, the reducing agent, and the changes in oxidation number that occur in the reaction. Chemistry 2019-02-14T00:00:00Z Using this oxidation number and the compound’s formula, guideline 4 may then be used to calculate the oxidation number for sulfur: Chemistry 2019-02-14T00:00:00Z According to guideline 2, the oxidation number for sodium is +1. Chemistry 2019-02-14T00:00:00Z Using the oxidation number concept, an all-inclusive definition of redox reaction has been established. Chemistry 2019-02-14T00:00:00Z In the nitrate ion, , the oxidation number for nitrogen is +5 and that for oxygen is −2, summing to equal the 1− charge on the molecule: Chemistry 2019-02-14T00:00:00Z The oxidation number of an atom in an elemental substance is zero. Chemistry 2019-02-14T00:00:00Z The oxidation number of a monatomic ion is equal to the ion’s charge. Chemistry 2019-02-14T00:00:00Z Guideline 3 suggests the oxidation number for oxygen is −2. Chemistry 2019-02-14T00:00:00Z Using this oxidation number and the ion’s formula, guideline 4 may then be used to calculate the oxidation number for sulfur: Chemistry 2019-02-14T00:00:00Z |
