金属元素钠、铝和铁是高考考查的核心内容,它们分别代表特活泼金属、两性金属和变价金属。各具特性的金属通过一定情境的“混搭”重组,可以全方位考查学生接受、整合化学信息的能力,分析和解决化学问题的能力,化学实验与探究的能力等。下面对各种“混搭”方式,举例分析。类型一:单质间的“混搭”
The metal elements sodium, aluminum and iron are the core content of the college entrance examination examinations, which represent the special lively metals, amphoteric metals and variable-price metals. Metals with different characteristics can be reorganized in a certain situation through “situational mixing” to fully examine students’ ability to accept and integrate chemical information, analyze and solve chemical problems, and experiment and explore chemistry. Below a variety of “mashup ” way, for example analysis. Type one: between the simplex “mashups”
