Teaching Objectives 1. Knowledge Objectives: To enable students to understand the physical properties of chlorine, and to initially grasp the chemical properties of chlorine and metals, hydrogen, and water bases. From the atomic structure of chlorine and the reaction of chlorine with metal, hydrogen, etc., it is known that chlorine is a very chemically non-metallic material. 2. Ability goals: To develop students’ ability to observe and analyze problems. Cultivate abstract abstracts of students and form the ability to summarize and summarize regular knowledge. Master the learning ideas of learning elemental compound knowledge. 3. Emotional goals: Through inquiry teaching, students’ interest in learning is stimulated, students are trained to love science, respect science, and they are rigorous, realistic and hard to explore.
