The most reactive metal. Though quite rare, it Is used in photoelectric cells and in atomic clocks.
Nicknamed Quicksilver, it is the only metallic element that is a liquid. It is used in barometers and used to be used in thermometers because it expands significantly when heated.
This meal is the best conductor of heat and electricity. It used to be found in coins, but now its too expensive to use it there. Its compounds are light sensitive and still used in photographic films.
A highly reactive metal whose compounds make up limestone, chalk, cement, and the bones and teeth of animals. Milk is a good source of this element.
A yellow nonmetal that occurs both free and in compound form in nature. It is used in match tips, gunpowder and rubber. Its presence in coal leads to acid rain if not removed before burning.
A hard magnetic element that is used in the production of steel. A radioactive form of this element is used in cancer treatment.
Used in borosilicate glass, drill bits, and control rods in nuclear reactors.
A low melting point metal. use din electrical fuses and in fire detection devices.
A sift highly reactive metals. Its compounds include lye, table salt and baking soda.
A reactive metallic element. Compounds are used to outline the intestines for Xrays. Compounds also Give green colors in fireworks
Never found as a pure element. It is essential in all cell protoplasm, DNA and animal tissues and bones. It is also present in fertilizers.
A metal used to make stainless steel. combined with nickel, it forms nichrome wire, where high conductivity produces heat.
An element with a symbol base on its Latin name. it is used with lead in car batteries.
A reactive silver white metal. that is second in abundance to sodium in ocean water. Its used in alloys due to its low density and high strength. its compounds like milk of magnesia and Epsom salts have medicinal uses.
A gaseous element that makes up 78 %of our atmosphere. its compounds are important components of proteins, fertilizers, and explosives.
One of three magnetic metallic elements. This element is used in 5 cent pieces and nichrome wire.
Highest Melting Point element. It is still present in old incandescent light bulbs, Its one letter symbol comes form the name wolfram.
This magnetic metallic element is used extensively for structural purposes.
A highly reactive metal. it is one of the three main elements in fertilizers. Similar compounds to sodium but more expensive.
A gaseous nonmetal, the most abundant element on earth. it makes up 21% of the earth's atmosphere.
An unreactive gaseous element that is produced from fusion in the sun. The second most abundant element in the universe
