英语单词“valence”的意思是:电价;亲和力;有效原子价;表现力。读音为:英 [ˈvæləns]、美 [ˈvæləns]。例句如下:
1. The chemical valence of a metal varies with its oxidation state. 金属的化学价随氧化态的不同而变化。
2. The strong positive valence of lithium is due to the electron arrangement of 2s^2^2p^1^. 锂正价强的原因是电子排列为2s^2^2p^1^。
3. The valence of oxygen is -2. 氧的化合价为-2。
4. The valence of the elements in the solution is usually determined by chemical analysis. 溶液中元素的化合价通常通过化学分析来确定。
5. The valence of the elements in an element's spectrum can be very large or small depending on its condition and/or presence in space. 元素谱线中的元素元素的电价根据它的状况以及它在宇宙中的存在可以是很大的也可以是很小的。
6. These atomic differences have effects on valence. 这些原子性差异会影响电子态并由此影响电子配对的情况。
7. The valence of a given element depends on its chemical environment. 一种元素的电价取决于它的化学环境。
8. The valence of oxygen is +2 and +4 in some compounds. 在某些化合物中氧的电价为+2和+4。
9. The valence bond theory of chemical bonding has been replaced by quantum mechanical theory. 化学键的电子配对理论已被量子力学理论所取代。
10. The valence bond theory is a theory of chemical bonding that explains how atoms combine to form molecules. 电子配对理论是一种化学键理论,它解释了原子如何结合形成分子。
