Questions: new classes for the type of atomic extra-nuclear electron decomplimentation 1 teaching objectives and core physiology of the subject teaching objectives: 1, understanding the characteristics of the atomic extra-nuclear electron movement; 2, mastering the atomic extra-nuclear electron decomplimentation patterns; 3, nuclear extra-embracing, capable of expressing common atoms (ion) with atom (ion) structure maps. Core nucleus: to develop students ' ability to analyse and process data through knowledge of the electro-temperature patterns of atomic nucleus, and to try to process information by comparing, summarizing, etc. The scientific approach and the correct attitude towards the research results of the predecessors are being developed and the right values are being built in the learning of the previous generations ' research history. (b) extra-nuclear e-teams that can be expressed in atom (ion) structure maps; 2. What are the particles made of? One, atoms are the smallest particles of chemical change. For atoms: nuclear charge = proton = extra-nuclear electrons = atomic sequences, we know that there are 11 electrons outside the sodium nucleus, and this 11 electrons are concentrated at the same distance from the nucleus, or dispersed at different distances from the nucleus? Information: characteristics of extra-nuclear electronics: (1) the mass of electronics is very small and carries a negative charge。
