Metalloids

Metalloids are a elements that are somewhere between a metal and nonmetal. They can be used to form alloys, and they have a metallic appearance. They also have nonmetal properties such a being brittle.

Are all viruses man made?

A computer virus is nothing more than a computer program. Same with Worms and Trojan Horse Programs. They're just code written by a person (or people, as the case may be.)

From the McAfee Security home page:

"Virus - A computer program file capable of attaching to disks or other files and replicating itself repeatedly, typically without user knowledge or permission. Some viruses attach to files so when the infected file executes, the virus also executes. Other viruses sit in a computer's memory and infect files as the computer opens, modifies or creates the files. Some viruses display symptoms, and some viruses damage files and computer systems, but neither symptoms nor damage is essential in the definition of a virus; a non-damaging virus is still a virus."

ALSO: "Worm - Worms are parasitic computer programs that replicate, but unlike viruses, do not infect other computer program files. Worms can create copies on the same computer, or can send the copies to other computers via a network. Worms often spread via IRC (Internet Relay Chat). "

AND: "Trojan Horse - A Trojan horse program is a malicious program that pretends to be a benign application; a Trojan horse program purposefully does something the user does not expect. Trojans are not viruses since they do not replicate, but Trojan horse programs can be just as destructive."

To answer your question, No, and sort of yes.

There are some viruses that modify themselves slightly during replication, and therefore become products of their own evolution, but even these were specifically written to do so by a human being.

What is the definition of metalloid?

A Metalloid Is An Element Which Has Intermediate Properties Between Metals & Nonmetals ;)
A product made of or to do with metal.
A metalloid can have properties of both metals and nonmetals. Some examples of metalloids are Boron, Silicon, Germanium and Arsenic.

What are metalloids?

The metalloids can be defined as those elements which exhibit characteristics of both metals and nonmetals. They are all solids, but not lustrous, and conduct heat and electricity moderately well.

The six metalloids treated here are listed below, with the atomic number and chemical symbol of each.

  • 05. boron (B)
  • 14. Silicon (Si)
  • 32. Germanium (Ge)
  • 33. Arsenic (As)
  • 51. Antimony (Sb)
  • 52. Tellurium (Te)
  • 84. Polonium (Po)

What are the characteristics of metalloids?

Metalloids, by definition, have properties of both metals and non-metals. Although chemical and physical differences can vary throughout the group. But the two general characteristics are that metalloids often form amphoteric oxides and often behave as semiconductors. They can be shiny or dull and their shape is easily changed.

Some characteristics of metalloids include:

  • Metalloids typically conduct heat and electricity better than nonmetals but not as well as metals.
  • They tend to sit on the fence during chemical reactions, taking electrons from most of the metals and will lose electrons to most nonmetals
  • Ionic bonding is rare, due to rule No 2. Covalent bonds are much more common.
  • They are solids.
  • They conduct heat and electricty.
  • They insulate at low temperatures.
  • They conduct at high temperatures.
  • The metalloids (B, As, Ge, Sb, Te, Si, Po) can be semiconductors; also form amphoteric oxides.

What properties distinguish metals from nonmetals?

Metals are usually more conductive. They have higher boiling and melting points, and lower electronegativity than other elements. Also, Metals are malleable and ductile, whereas non metals are not.

Is krypton a metal non metal or metalloid?

Not only is the Periodic Table of Elements classified by solids, liquids, and gases, it's also classified by metals, nonmetals, and metalloids. Kyrpton is a metal.

it is a nonmetal gass that was discovered by Sir William Ramsay and Moris M. Travers on May 30th 1898

Why silicon is preferred over germanium in the fabrication of p-n junction diode?

Germanium diodes are more expensive than silicon ones, germanium is harder to process, germanium cannot be used to make integrated circuits (while early prototype integrated circuits were germanium the wiring between the integrated components cannot be integrated making it too expensive for production), germanium cannot operate with a junction temperature above 60C (silicon will operate up to 150C), and its reverse leakage current is greater. However! Germanium diodes have a lower forward voltage drop than silicon ones do, so they're better for some applications, like radio frequency detection.

Why are metalloids called metalloids?

Metalloid elements are called so because they share properties of both metals and nonmetals. Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium make up most of the metalloids.

Compare flex vs metal duct?

Flex -VS- Ridged ductingThere is not a better or worse as far as flex vs. ridged. There is however a better or worse application of each.

Flex duct was designed to be used as a �Last 6 Feet� connector for drop ceiling applications. For this purpose there is nothing better. It also works great for multi radius connections over a short length (6 ft or less).

Ridged pipe is much better suited for longer, straighter runs. The pipe is much less restrictive and has a lower friction loss due to its smooth interior.

The ASHRE Design manual has great information on use of ducting materials.

Flex has become the materials of choice for ducting runs, only because the installers have become lazy and the company owners have become greedy. The installation cost is reduced because there is little or no time spent measuring and cutting duct to fit the application. Flex can be strung through rafters, over and around perlins, and comes in 25 ft lengths (shorter than most runs) reducing cuts and splices. It can also be strung too tight, smashed and bent to unreasonable restrictions and seldom if ever properly supported.

If used properly, flex is better than hot buttered toast. Done wrong, and reduced airflows, extreme temperature differentials and overall poor efficiency is the only possible outcome.

Where are metals found in the periodic table?

Metals are found on the left hand side on the periodic table (towards the left of the "staircase". The "staircase" line divides elements into metals and non-metals. Elements to the right of the "staircase" are the non-metals. However, those close to the staircase have both metallic and non-metallic properties and hence are called metalliods.
