27 paź 2022 · The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table. These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals.
Physical properties are listed in order of ease of determination; chemical properties run from general to specific, and then to descriptive.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties. All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Metalloid characteristics and properties. Metalloids occupy a unique position in the periodic table, exhibiting properties that bridge the gap between metals and nonmetals; Atomic radius of metalloids generally decreases from left to right across a period, influencing their chemical and physical properties
The physical properties of metalloids tend to be metallic, but their chemical properties tend to be non-metallic. The oxidation number of an element in this group can range from +5 to -2, depending on the group in which it is located.
Physical Properties of Metalloids. State: They are all solid at room temperature. Conduction: Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semi-conductors.
