---|---|
An unreactive, gaseous element that is a product of the nuclear reaction of hydrogen atoms. | Helium-He |
Areactive, metallic element, used as a medical cocktail for X-Ray. | Barium-Ba |
A highly reactive metal. Used in the manufacture of synthetic rubber and drugs. Nuclear weapons. | Lithium-Li |
A widely disturbed nonmetal. Essential component in all cell protoplasm, DNA, and carious animal tissues and bones. | Phosphorus-P |
An unreactive gas. Could weaken Superman. Its presence in the atmosphere can indicate whether a nation is testing nuclear weapons. | Krypton-Kr |
A reactive metal with a high melting point. Used in manufacturing rocket nose cones because this low-density substance is remarkably strong. | Beryllium-Be |
A reactive, silver-white metal that is second in abundance to sodium in ocean water. Epsom salt and milk of magnesia. | Magnesium-Mg |
A component of all living matter and fossil fuels; the black material on a charred candle wick. | Carbon-C |
Nicknamed "quicksilver", only liquid metal at room temperature. Used in thermometers because of expantion. Toxic "heavy" metal. | Mercury-Hg |
The lightest and most abundant element; the fuel of the universe. | Hydrogen-H |
A highly reactive metal of low density. 1/3 main elements found in fertilizer. Similarto sodium though more epensive | Potassium-K |
A soft, dense metal used in bullets and car batteries. | Lead-Pb |
Highest melting point.filament in ordinary light bulbs. Symbol comes from the name wolfram. | Tungsten-W |
A metallic element. Added to steel to increase its strength. | Manganese-Mn |
A metallic element. Electrode in the flashlight battery, alloyed with copper becoming brass. | Zinc-Zn |
A metal that is used to make stainless steel. Combined with nickel to make nichrome wire. | Chromium-Cr |
The most chemically reactive metal. Used in some photoelecrtic cells and in atomic clocks. | Cesium-Cs |
A reddish, lustrous, ductile, malleable metal that occurs in nature in both free and combined states. | Copper-Cu |
This magnetic, metallic element is used extensively for structural purposes. Outdoor stair railings may be made of this element. | Iron-Fe |
A yellow, nonreactive, metallic element that has been highly valued since ancient times for its beauty and durability. | Gold-Au |
A metallic element that is used as a corrosion-resistant coating on the inside of cans used for packaging food, oil, and other substances. | Tin-Tn |
A highly reactive, gaseous nonmetal. Its compounds are added to some toothpastes and many urban water supplies to prevent tooth decay. | Fluorine-F |
A reactive metal whose compounds make up limestone, chalk, cement, and the bones and teeth of animals. Milk is a good nutritional source of this element | Calcium-Ca |
An expensive, silver-white metal used in jewelry. Also used to speed up chemical reactions. | Platinum-Pt |
A solid purple-black nonmetal that changes to a deep purple gas upon heating. | Iodine-I |
Used in borosilicate glass, Boraxo soap, drill bits, and control rods in nuclear ower plants. | Boron-B |
1/3 of the 3 magnetic elements, this metal is used on a 5-cent piece and other coins, in electroplating, and in nichrome wire. | Nickel-Ni |
The most abundant metal in Earth's crust, this silver-white element is characterized by its low density, resistance to corrosion, and high strength. Used for airplanes, boats, and cars. | Aluminum-Al |
A hard, magnetic metal used in the production of steel. | Cobalt-Co |
A silve-white, lustrous, radioactive metal. Its oxide is used as fuel in nuclear power plants and in atomic warheads. | Uranium-U |
An unreactive, gaseous element used in advertising signs for the bright reddish-orange glow it produces when an electric current is passed through it. | Neon-Ne |
A yellow nonmetal that occurs in both the free and combined states. It is used in making match tips, gunpowder, and vulcanized rubber. | Sulfur-S |
This metal is the best conductor of heat and electricity. Its scarcity prevents it from common use for such purposes. | Silver-Ag |
A gaseous nonmetal, the most abundant element on Earth. It makes up some 21% of Earth's atmosphere and is essential to most forms of life. | Oxygen-O |
The second most abundant element in Earth's crust. It is the principal component of sand and quartz and finds use in solar cells, computer chips, caulking materials, and abrasives. | Silicon-Si |
A metallic element used in nuclear power plant control rods and in NiCad rechargeable batteries. | Cadmium-Cd |
A red, highly reactive, fuming liquid with a foul smell. It finds limited use as a disinfectant. | Bromine-Br |
An odorless, colorless, unreactive gas used in most incandescent light bulbs. | Argon-Ar |
An element with a symbol based on its Latin name. | Antimony-Sb |
A soft, highly reactive metal.Its compounds include table salt, lye, and baking soda. | Sodium-Na |
A gaseous nonmetal that makes up 78% of Earth's atmosphere. Important components of proteins, fertilizers, and many explosives. | Nitrogen-N |
A highly reactive, greenish-yellow gas used as a bleach and water disinfectant.Component of table salt. | Chlorine-Cl |
