原子核与核外电子构成了原子,其中这些电子围绕原子核的中心运转.原子结构与性质是在必修2已有知识的基础上进一步研究原子的结构,从构造原理和能量最低原理介绍原子的核外电子排布以及原子光谱、电子云和原子轨道;在原子结构知识的基础上,进而研究元素周期表及元素周期律.结合考点阐释在高考中的原子结构的考查方式和类型. Nuclear and extranuclear electrons constitute atoms, of which these electrons operate around the center of the nucleus. The atomic structure and properties are further studied on the basis of the compulsory knowledge of the structure of the atom, from the principle of construction and the principle of the lowest energy, Electronic arrangement and atomic spectroscopy, electron cloud and atomic orbit; based on the atomic structure of knowledge, and then study the periodic table of elements and the periodic law of the elements.Combined with test centers to explain the structure and type of test in the entrance exam.
