一、运用形声字的知识,提高识记化学元素的效率化学的学习,其中一个重要内容就是要记住足够数量的化学元素,还要分清各属于哪一类。但是化学元素众多,单凭死记硬背,是记不了那么多的,而且就是能记住也须花费太多的时间和精力。在化学学科中,绝大多数是用形声字表示各种化学元素的名称,可以根据这个形声字的造字规律来直接判断和识记各种化学元素是属于哪一种类型。这样所费的精力和时间少,效果也很好。1.金属类的化学元素的名称,一般都有金字旁作形旁,可以根据这个特点判断一种化学元素是否是金属类元素。
First, the use of shaped words of knowledge to improve the efficiency of chemical elements of knowledge of chemical learning, one of the important elements is to remember a sufficient number of chemical elements, but also distinguish which one belongs to each category. However, there are many chemical elements, which can not be remembered by mere rote learning. And it takes too much time and energy to remember. In chemistry, most of them use the form of sound word to denote the names of various chemical elements. According to the law of character formation of this shaped sound, it is possible to directly judge and recognize which type of chemical element belongs to. This effort and less time spent, the effect is also very good. 1. The names of metal chemical elements, generally next to the shape beside the word, according to this feature can determine whether a chemical element is a metal element.
