阳信一中化学必修二复习提纲（Yangxin No. 1 middle school chemistry required two review outline） Chapter 1 atomic structure and periodic law of elements 1. atom structure: For example, the relation between proton number and mass number, neutron number, electron number Periodic table and periodic law of 2. elements (1) the structure of periodic table of elements A. cycle number = Electron layer number B. atomic number = proton number C. principal group ordinal = outermost electron number = the highest positive valence of an element The number of negative valence D. group of non-metallic elements = 8 main group number E. periodic table structure (2) periodic law of elements (emphasis) Comparison of metallicity and metallicity of A. elements The reaction between A. and water or acid, the difficulty of exchanging hydrogen or the difficulty of hydrogen combination and the stability of gaseous hydride The high B. oxide hydrate of alkaline or acidic strength The reducibility or oxidation of C. elements (Note: the reverse of the change of the properties of a single element with the corresponding ion) Variation of properties of B. elements with cycles and families In the same cycle of A., the metallicity of elements decreases from left to right B. in the same cycle, from left to right, elements of non-metallic gradually increased C. the same family, from top to bottom, metal elements gradually increased D. same family, from top to bottom, non-metallic elements gradually weakened Changes of the elements C. third cycle variation and the alkali metals and halogen elements (including physical and chemical properties) Comparative law of the radius of D. particles: A. atoms and atoms B. atoms and their ion C. electronic layer structure of the same ion (3) application of the periodic law of elements (heavy and difficult points) A., bit, structure, sex of the relationship between the three The A. atomic structure determines the position of the elements in the periodic table of elements The atomic s
