化学元素的周期性与原子的电子层结构密切相关。因此凡是和类似的电子构型有关的一切性质都应呈现出周期性的变化。但是这种变化并不是简单的重复,而是依一定方向作有规律性的变化。本文以周期系为基础,讨论简单无机含氧酸的结构及其强度规律的周期性,加深对周期律实质的理解。一、常见无机含氧酸结构规律的周 The periodicity of the chemical elements is closely related to the atomic electron structure. Therefore, all the properties associated with similar electronic configurations should exhibit periodic changes. However, this change is not a simple repetition, but a regular change in a certain direction. Based on the periodic system, this paper discusses the periodicity of the structure and intensity law of simple inorganic oxyacids and deepens the understanding of the essence of the periodic law. First, the common inorganic oxygen acid structure of the week
