When shopping for a smartphone, the single most important feature that people look for is the display. Department of Energy dubbed them the “technology metals.” Rare-earth elements are so important in the electronics, communications, and defense industries that the U.S. They are found in televisions, computers, lasers, missiles, camera lenses, fluorescent light bulbs, and catalytic convertors. Rare-earth metals are not only used in smartphones but in many other high-tech devices, too. Also, your phone would not be able to vibrate without neodymium and dysprosium. Many of the vivid red, blue, and green colors you see on your screen are due to rare-earth metals, which are also used in the phone circuitry and in the speakers. The only one you will not find is promethium, which is radioactive. If you examine several varieties of smartphones, you can find 16 of the 17 rare earth metals.
Scandium and yttrium are included in the rare-earth metals because their chemical properties are similar to those of the lanthanides.Ī single iPhone contains eight different rare-earth metals. The lanthanides often appear as the first of two free-floating rows located at the bottom of the periodic table. Elements 57–71 are known as the lanthanides, because they begin with the element lanthanum. These rare-earth metals include scandium and yttrium, as well as elements 57–71. One rather obscure group of metals-the rare-earth metals-plays a vital role. Metals are what make smartphones so “smart.” An average smartphone may contain up to 62 different types of metals. Of the 83 stable (nonradioactive) elements, at least 70 of them can be found in smartphones! That’s 84% of all of the stable elements. If you are wondering what chemistry has to do with smartphones, just look at the periodic table. None of this would be possible without chemistry, and every time you use your smartphone, you are putting chemistry into action. Amazingly, you can surf the Internet, listen to music, and text your friends with something that fits in the palm of your hand. Even a low-end smartphone has more computing power than the computer system the National Aeronautics and Space Administration (NASA) used to put a man on the moon. In the 1950s, you would have needed a whole bank of computers on an entire floor of an office building to do what you are able to do with a single smartphone today. If you own a smartphone, you are probably aware that in a year or two, it will be practically obsolete, because the smartphone just keeps getting smarter.
Worldwide, more than one billion smartphones were purchased last year.
And now the cell phone has morphed into something bigger and better-the smartphone. It is hard to believe that 20 years ago, hardly anyone even owned a cell phone. residents could not, according to a recent poll conducted by Time magazine. Could you last a day without your cell phone? As many as 84% of U.S.
