On earth, all elements are divided into three categories which are metals, metalloids, and nonmetals. Among all elements, some are essential while some metals, metalloids, or nonmetals are hazardous. Lethal or toxic heavy metals like arsenic, mercury, lead, selenium, etc. should be treated to...

METALS are the best conductors of heat. This is because the electrons in metals move more freely than in non-metals, allowing the heat energy to travel across the metal. Metals have few electrons in their outer energy level. For example, when the spoon touches the hot drink, the heat from...
Between the metals and nonmetals is a group of elements known as either thesemimetalsor themetalloids, which are elements that have properties intermediate between those of the metals and nonmetals. Most metalloids have a shiny, metallic appearance but are brittle, unexceptional electrical conductors ...

The elements possessing physicochemical properties intermediate to metals and non-metals are known as metalloids. Silicon (Si), boron (B), arsenic (As), antimony (Sb), germanium (Ge), tellurium (Te), etc. fall under this category. Metalloids are being used in many applications including semico...
