“原子和原子核”一章是每年高考的必考内容,年年有试题涉及,是高考考查的热点.在原子模型中,以玻尔理论和原子能级命题频率最高,在原子核组成、核能中,以衰变规律、核能计算命题频率最高,其他知识点尽管也时有出现,但命题频率较低.现对2007年全国12套高考物理试题进行归类赏析
The chapter “Atoms and Atomic Nuclei” is a must-examination content for the annual college entrance examination. There are examination questions every year and it is a hot spot for the college entrance examination. In the atomic model, Bohr theory and atomic energy level have the highest frequency of propositions, and in the nuclear composition and nuclear energy, The frequency of propositional calculations is the highest with decay laws and nuclear energy. Other knowledge points appear frequently, but the frequency of propositions is low. Nowadays, 12 physics examination questions in the national college entrance examination are classified and appraised in 2007.
