摘要
生命的化学过程如同任何化学过程一样,其本质都与反应物之间的电性相互作用有关。实验表明含水络合离子的半径(r_w)远远大于纯离子的半径(r_o);r_w-r_o=r的大小反映离子外部含水保护层的厚度。当元素处于离子状态或是原子状态时,对外吸引电子或对外放出电子的固有性能,即与电负性(x)有关系。因此,一个含水络合的离子或含水团聚型离子对外亲电性大小是由上述三种因素协同起来作用。据此,作者定量提出了生命相关元素的含水络合的亲电、亲核强度标度理论,并按生命相关元素电荷强度的大小将离子群体分为八类,并对各类的作用作了诠释。
Like any chemical processes, the chemical process of life is related to the interaction of the electronicity of reactants in essence. Experiments show that the radius of hydrated ion (rw) is much bigger than that of pure ion (ro) and rw- ro=△r reflects the aquifer thickness of ions. Any element, either in the atomic state or in the ionic state, is always surrounded by different atom clusters and thus it has the intrinsic characters of attracting or emitting electrons, i.e., electronegativity. Thererefore, the electronegativity of hydrated complex ions or hydrated ions is determined by the actions of the above-mentioned three factors and on this basis the authors of this article put forward the theory on the scale of nucleophilic and electrophilic strength of hydrated complex of life-related elements and divide this kind of elements into eight classes according to their electric charge strength and explain the functions of each of them in this paper.
