Materials that are poor conductors of electricity are calledinsulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons. ... So among the following options aluminum,
Why are ionic solids poor conductors of electricity? Is iron a metal, nonmetal or metalloid? What charge do nonmetals have? What elements are the poorest conductors of electricity? Which are more common: metals or nonmetals? Do nonmetals have high or low boiling points?
(a) Explain why(i) metals are good conductors of electricity,(ii) insulators do not conduct electricity.[3] 相关知识点: 试题来源: 解析 (a) mark (i) and (ii) together:mention of free electrons(current is) flow/movement of free electronsinsulators contain no free electrons / metals contain...
Almost all good conductors of electricity known to man are metals or alloys. The problem of using exposed metal as conductors in electronics is that they tend to oxidize rather rapidly. Oxidized metals then go on to become poor conductors of electricity. ...
Metals are good conductors of heat and electricity because they contain a glut of free electrons. These free electrons are able to move around freely and collide with one another, propagating heat and electricity through the metal. The majority of materials that conduct heat and electricity are m...
原句"All these metals are not good conductors."属于英语中的部分否定结构。"All...not"的语义为"并非所有",而非字面化的所有个体都被否定。原中译"都不是良导体"使用了完全否定结构,错误地表示没有金属能导电。正确表达需要突出"不全然"的否定逻辑,"并非都是良导体"准确对应了"部分金属不导电"的原文语义,...
Why do nonmetals tend to form anions when they react to form compounds? Why can't the halide ions be oxidizing agents? Why do metals only form ionic compounds while metalloids and nonmetals form ionic and covalent compounds? Why are metals good conductors of electricity?
