What property of semi-metals are useful in the electronic industry?
semi-conducting
What are the important ores?
Their importance is that these ores can be extracted into metals .
Is electronic equipment a nonrenewable resource?
Electronic equipment is made of many substances, including rubber, metals, glass and plastics. Metals in general are non-renewable. In general, plastics are non-renewable as they are derived from oil. Glass is renewable resource, but we are consuming fossil fuels to transform silicon particles (sand) into glass. For this reason, glass should be recycled. More importantly, there has been a huge turnover of electronic equipment, creating hazardous conditions when disposed in incinerators or landfills. The disassembly of electronic equipment and re-use is a growing and important industry. There is a worldwide effort to recycle or carefully dispose of the plastics used in all electronic equipment (from telephones, televisions, cameras, computers, fax machines, ipods, and many others) as there are chemical hazards (heavy metals in particular) to the environment when large quantities enter landfills. You can find out if there are special measures being taken in your community for recycling computer equipment. All the major manufacturers of PC's are aware of "e-waste." I've included some links.
What is a mineral containing 2 or more metals?
A mineral containing two or more metals is known as a polymetallic mineral. These minerals can be important sources of multiple metals, such as copper, lead, zinc, and silver, often found in ores like galena (lead sulfide) or sphalerite (zinc sulfide). Polymetallic deposits are valuable for mining as they allow for the extraction of several metals simultaneously, improving economic efficiency.
What is the difference between precious metals and precious minerals?
Just as the name implies- precious metals are metals- things that conduct electricity, have luster, ductility and malleability- and are rare. Examples include gold, silver, platinum, palladium, etc. Precious minerals- just that- minerals- defined as naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color, and hardness. To be precious, they also would be rare and sought after. Examples may include diamonds, rubies, emeralds, etc.
What metals and non metals are used in computers and electronic devices?
Metals commonly used in computers and electronic devices include copper (wiring), gold (connectors), aluminum (heat sinks), and iron (steel casing). Non-metals like silicon (semiconductors), carbon (plastic components), and oxygen (used in insulating materials) are also essential in electronic devices.
What are the properties and applications of dielectric metal in electronic devices?
Dielectric metals are materials that have both insulating and conducting properties, making them useful in electronic devices. They can store and release electrical energy, making them ideal for capacitors and energy storage devices. Dielectric metals are also used in antennas, sensors, and other electronic components where a combination of electrical conductivity and insulation is needed.
What pollutant is associated with electronic equipment discarded in landfills?
Several metals, including lead and mercury, are included in electronic devices that should be recycled and not disposed of in landfills.
What electronic component was widely used in electronic devices before solid state components were developed?
Elements found between the metals and nonmetals are called metalloids. Hope that helped!
Is germanium a non metal or metal or metalloid?
Germanium is a metalloid. It exhibits properties of both metals and non-metals, making it a semiconductor commonly used in electronic devices.
What important characteristic do the alkali metals ad alkaline earth metals have in common?
Thet are all highly reactive. They react with oxygen (air) , water and acids. The further down the Groups, they become more reactive, to the point of explosion. The metals react with oxygen to form the metal oxide (bases). The metals react with water to form metal hydroxides (alkalis) and hydrogen The metals react with acids to form chemical salts and hydrogen . In terms of reactivity, Francium , reacts the same as other Group (I) & (II) metals, but is not found in the 'open' lab. because it is also radio-active.
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
What is a characteristic of nonmetal a?
One characteristic of non-metals is that they are generally gaseous at room temperature. Non-metals will also typically bond with metals easily.
Which materials is not a good insulator?
Metals are not good insulators as they have high thermal conductivity, allowing heat to pass easily through them. This is why metals are commonly used as conductors in electrical circuits or as heat sinks in electronic devices.
Bacteria are not used to make?
Bacteria are not used to make larger electronic devices like smartphones or computers. These devices are typically manufactured using a combination of metals, plastics, and other materials that are not produced by bacteria.
Is a metalloid a semiconductor?
Yes, a metalloid is a type of element that has properties of both metals and nonmetals. Some metalloids, such as silicon and germanium, are commonly used as semiconductors in electronic devices.
What is one characteristic of a nonmetal?
Metals conduct electricity; non-metals do not.
