whose atoms have identical arrangements of electrons in their highest energy levels have similar properties and make up a family of elements in the periodic table (vertical columns). Elements on the Periodic Table are grouped into metals, nonmetals and metalloids based on some key physical and ...
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…
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. ...
An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities,...

What About Metalloids? In addition to metals and nonmetals, there are also metalloids on the periodic table. Metalloids are unique because their properties fall somewhere between those of metal and nonmetal elements. They aren’t particularly lustrous, nor are they are particularly dull. Rather, th...
