oxidation number

基本解释

Three steps are needed by using "total number of rising and dropping oxidation number" to balance equation.
配平氧化还原反应方程式的原则是：还原剂氧化数升高的数值等于氧化剂氧化数降低的数值。
We'll get to oxidation number in the second half of this course, but it's not in any way the same idea as formal charge.
我们会在课程的后半部分讲到氧化数，但它和形式电荷完全不是同一个概念。
Behavior: These elements were considered to be inert gases until the 1960s, because their oxidation number of zero prevents the noble gases from forming compounds readily.
反应性质：直到20世纪60年代，这些元素都被认为是惰性气体。这是因为：这些元素的氧化数是0，这使稀有气体不容易形成化合物。
