Name that element! What element found in meteorites can strengthen steel, power model airplanes, and color glass green? Follow these eight clues to find out.(CLUE 1)
In its pure form, the mystery element is a silvery white metal. The majority of this element on Earth is found in the planet's core, or center. However, there are deposits closer to Earth's surface Noun 1. Earth's surface - the outermost level of the land or sea; "earthquakes originate far below the surface"; "three quarters of the Earth's surface is covered by water"

The United States is the world's third largest country in population and the fourth largest country in area. gets half its supply of this element from mines in Canada and Australia. It gets the other half through recycling programs that collected about 119,000 tons of the element in 2007.

The National Museum of Natural History in Washington, D.C. The origin of the mystery element in a major Canadian mine is thought to be the result of a meteorite meteorite, meteor that survives the intense heat of atmospheric friction and reaches the earth's surface. Because of the destructive effects of this friction, only the very largest meteors become meteorites. impact that heated up Earth's outer layer, or crust, creating a deep pool of metal-rich magma. As it cooled, the metals sank and formed deposits.

When you fly a model airplane, you're using the power from rechargeable batteries that contain the mystery element. These special batteries are preferred for the motors in model airplanes because they release their charge faster and at a higher voltage than other rechargeable batteries. This gives the motor more power. During flight, the electric current flows from the anode anode (ăn`ōd), electrode through which current enters an electric device. In electrolysis, it is the positive electrode in the electrolytic cell.
Terminal or electrode from which electrons leave a system. , or negative terminal, made of cadmium (Cd) to the positive cathode made of the mystery element.

While clear glass is useful for windows and eyeglasses eyeglasses or spectacles, instrument or device for aiding and correcting defective sight. Eyeglasses usually consist of a pair of lenses mounted in a frame to hold them in position before the eyes. , sometimes a little color helps spice things up. To tint glass green and blue, early glassmakers used compounds containing the mystery element and cobalt (Co), which is in the same period (row) as the mystery element. Some green and blue glazes for ceramics also contain small amounts of these compounds.

You can thank this element for turning the oil that makes French fries into the margarine you spread on your toast. To make margarine, vegetable oil and hydrogen are heated together using the mystery element as a catalyst to speed up a chemical reaction. This is called hydrogenation. But don't thank it too much: This process is also responsible for the trans fats that raise levels of "bad" cholesterol in blood, which can lead to heart disease.

When the mystery element is alloyed, or combined, with steel and chromium (Cr), the result is stainless steel stainless steel: see steel.
Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. . This is a stronger material that resists rusting better than regular steel.

Except for the penny, every coin circulating in the U.S. contains an alloy that is 25 percent of the mystery element and 75 percent copper (Cu), a metal having one more proton than the mystery element. In December 2006, the value of the metal in the coin named after the mystery element surpassed the face value of the coin. However, this past summer, the prices of the metal dropped, making the face value the winner again.

Anatomy of an Element
??-- Element symbol
x.xxxx--Average atomic mass atomic mass, the mass of a single atom, usually expressed in atomic mass units
ATOMIC NUMBER atomic number, often represented by the symbol Z, the number of protons in the nucleus of an atom, as well as the number of electrons in the neutral atom. Atoms with the same atomic number make up a chemical element. equals the number of protons (positively charged particles) in an atom's nucleus, or center. Every element contains a different number of protons, and so has a unique atomic number. In a neutral atom, the number of protons and the number of electrons (negatively charged particles) are equal.
ATOMIC MASS equals the number of protons plus the number of neutrons (uncharged particles) found in a single atom of an element. The atom's mass is in its nucleus, which houses both protons and neutrons.

* According to a study by scientists at Brown University, 10 out of 22 cell phones tested contain nickel. For people allergic to nickel, it can lead to a skin rash on the ear, cheek, or fingers. Such skin rashes have become so common that the British Association of Dermatologists has given a name to the condition: mobile phone dermatitis dermatitis (dûr'mətī`tĭs), nonspecific irritation of the skin. The causative agent may be a bacterium, fungus, or parasite; it can also be a foreign substance, known as an allergen. . The researchers recommend that people allergic to nickel who are its the market for a new cell phone use a special test kit to see if a phone contains nickel before purchasing it.
* Nickel is involved in hydrogenation, a process in which liquid oils are made into solid fats by adding hydrogen. This process forms trans fats, which may cause health problems for people who consume them. Trans fats turn up in french fries, cookies, crackers, and even hot-chocolate mix. The FDA FDA

(The ban contains some exceptions. For instance, restaurants can serve foods that come in the manufacturer's original packaging even if the food contains trans fats.) The board's reasoning for the ban is that the foods containing trans fats are unhealthy. Should the government be able to tell restaurants what they can and can't serve?
HEALTH: Seventeen percent of Americans have a skin allergy to nickel. Perform research to find answers to the following questions: What types of common items contain nickel? What other types of skin allergies exist? What can a doctor do for patients who have skin allergies?
