Berthollet, Davy,andGayLussacall expressed doubts at one time or another as to whether there really was a singleuniqueacidifyingprinciple. 贝托莱、戴维和盖·吕萨克都曾一度对是否真的存在一种独特的酸化原理表示怀疑。 Davy, in his original work on HCl, suggested that chlorine, being electronegative ...
Fig. 1.1.The structure of hydrogen atom. The hydrogen atom can be represented by the symbol H and a dot that stands for the single electron in the neutral atom. In its lowest energy form, the electron occupies the 1s orbital, spherically symmetrical around the hydrogen nucleus. In the secti...
