A further study. Exam notes, enhance targeted review She demanded: common metal elements (such as Na, Al, Fe, Cu) as an example: 1. understand the activity sequence of common metal. 2. understand the common metals and their compounds are important properties and applications. 3. understand the concept of alloy and its application. 4. combined with the comprehensive application of non metals and compounds, physical structure of the periodic law of elements and other parts of knowledge. Although the syllabus for knowledge requirements of metal part length less, but involves the content is more, the chemical knowledge as the reality of work and life, especially the hot social knowledge; of chemistry map, electronic and atomic structure of writing; the knowledge of the test vectors for comprehensive chemical substances in calculation of A Vogadero constant; as the center; the periodic law of elements and the application of the periodic table of elements, and structure, the relationship between the writing and the true or false; ions and ion equation; electrochemistry; smelting and metal corrosion; Fe (II), Fe (III) into each other; Al important compounds and image problems no, not involved in the metal part of the knowledge. Two. In recent years the national college entrance examination volume part examine the contents of metals and their compounds and cognitive level 1.2010 years of metals and their compounds part related knowledge test content and cognitive level The knowledge and ability
