无机推断题具有明显的化学学科特点,几乎是每年高考的必考题型,此类题型涉及元素周期表、元素名称符号等的表示方法,化学式、化学反应方程式及离子方程式,元素单质、重要无机化合物及其相互间的转换关系等知识的相互结合。解答此类题常用的思维方法有顺逆推断、猜想论证、综合分析等,但不管用何种方法求解,关键是抓住元素单质及其 Inorganic inference questions have obvious characteristics of chemistry, almost every year the exam will be the exam questions, such questions related to the periodic table of the elements, the element name symbols, etc., chemical formula, chemical reaction equations and ionic equations, elemental elements, important inorganic Compounds and their mutual conversion between knowledge and other mutual combination. The common way of thinking to answer such questions is inference, conjecture, comprehensive analysis, but no matter what method to solve, the key is to seize the elemental and its
