Examples of metalloids are boron, germanium, arsenic, silicon, tellurium, polonium and antimony. These elements exist in the realm between metals and non-metals and can have properties of both.Know More
Scientists agree that "metalloid" is a vague term, and even an element usually thought of as a true metal, such as aluminum, might be classified as a metalloid.
Often metalloids have the luster of metal but are brittle in a way that real metals are not. They can generally be alloyed with metals and are useful as semiconductors and flame retardants. They're also used in fireworks, signal lights and flares.
Some metalloids, taken in trace amounts, support good health. These include silicon, boron, and even arsenic in incredibly tiny amounts, though arsenic in any appreciable quantity is toxic. Boron and silicon are used as insecticides, and both have medical applications. Boron in the form of boric acid can treat infections and silicone gel treats burns.
Most metalloid oxides can be used to make glass. Boron trioxide is used to make glass ovenware, while silicon dioxide has long been used to make regular glass.
Silicon is famous as a semiconductor. At first, germanium was used as a semiconductor till silicon proved less expensive, easier to work with and better able to tolerate high temperatures.Learn more about Organic Chemistry
Decomposers include certain types of bacteria, worms, slugs, snails and fungi. All of these organisms break down or eat dead or decomposing organisms to help carry out the process of decomposition. They are the last step in the food chain, which recycles nutrients and breaks down wastes and organic matter in the ecosystem.Full Answer >
Examples of inorganic substances include all metals, ammonia, hydrogen sulfide, chlorine, salt, minerals such as gypsum and generally all compounds that do not contain carbon-hydrogen bonds. By definition, an inorganic substance is a substance that does not contain carbon.Full Answer >
An organic chemical is any molecule with at least one carbon atom forming its base, and a few examples of organic molecules include living matter such as the DNA of plants and animals, nonliving naturally occuring matter such as methane, fossil fuels and diamonds, and man-made materials such as carbon fiber.Full Answer >
Examples of being proactive are packing a briefcase the night before a meeting, reducing the risk of crime by hiring additional police officers and doing laundry before all the clothes are dirty. Proactive means acting in expectation of future needs or problems.Full Answer >
