“金属活动性顺序”是初中化学中的重点和难点,也是中考化学的热点考查内容之一。为帮助大家了解这一考点的命题方向及题型,走出解题误区,现举例说明。一、考查金属活动性顺序的内容K、Ca、Na、Mg、Al、Zn、Fe、Ni、Sn、Pb、(H)、Cu、Hg、Ag、Pt、Au “Metallic activity order ” is the focus and difficulty of junior high school chemistry, but also one of the hot spots in the exam chemistry. To help you understand the proposition of this test center the direction and type of questions, go out of the problem-solving errors, are an example. First, to examine the content of the order of metal activity K, Ca, Na, Mg, Al, Zn, Fe, Ni, Sn, Pb, (H), Cu, Hg, Ag, Pt, Au
