viz., elements, compound, and mixture. Elements are the purest forms of the matter among these three forms and again fall into three categories; metals, non-metals and metalloids. These three elements are bifurcated on the basis of their physical and chemical properties. ...
Metal is a category of elements with high conductivity, while steel is an alloy mainly of iron and carbon.
metalloid(译作“类金属”)、quasimetal(译作“准金属”)二词含义相同,主要用于化学领域。暂无严格定义,通常泛指外观类似于金属但物理或化学性质介于金属与非金属之间的材料。可能不同的论文代指不同的材料…

The element is divided into metal, metalloids and non-metals. Metals show good conductivity and form cation after losing the electrons. They contain free electrons that are responsible for their conductivity. Answer and Explanation:1 It is given that the metal and wood are kept at ...
Explain why the periodic trends for metal and non-metal reactivity are opposites. Chemical Reactions: At the atomic level, chemical reactions are due to the sharing or transfer of electrons to increase stability (more energetically favorable). Metals tend to lose valence electrons so ...
