Lutetium is a chemical element with the symbol Lu and atomic number 71. It is a silvery white metal, which resists corrosion in dry air, but not in moist air.
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Potassium is a chemical element with the symbol K and atomic number 19. It is a silvery-white metal that is soft enough to be cut with a knife with little force.
Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by the English chemist William Hyde Wollaston.
Radium is a chemical element with the symbol Ra and atomic number 88. It is a alkaline earth metals.
Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white.
Aluminium is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal. By mass, aluminium is the most abundant metal in the Earth's crust.
Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91. It is a dense, silvery-gray actinide metal which readily reacts with oxygen, water vapor and inorganic acids.I
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized.
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid alkaline earth metals.
Lanthanum is a chemical element with the symbol La and atomic number 57. It is a soft, ductile, silvery-white metal that tarnishes slowly when exposed to air and is soft enough to be cut with a knife.
Cerium is a chemical element with the symbol Ce and atomic number 58. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife.
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic is a metalloid and occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.
The technology that keeps huge cargo ships afloat is amazingly simple. A student in Naval Construction and Engineering at MIT explains just how simple it really is. Part of the "Science Out Loud" series.

Gold is a chemical element with the symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile trasition metal.
Students learn what makes science different from other disciplines. They also explore the many exciting career opportunities in the science filed. Concepts and terminology discussed include: observing, solving problems, health, career, education, and sharing information.
Did you know that cars can be recycled. In this episode, Joel witnesses the massive power of the car crusher and learns how the different parts of cars can be reused. Part of the Curiosity Quest Series.
This award-winning documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory, examines how LIGO is spearheading the new field of gravitational wave astronomy and opening a whole new window on the universe. LIGO's exquisitely sensitive instruments may ultimately take scientists farther back in time than ever before, catching, perhaps, the first murmurs of the universe in formation.
Learning to incorporate a variety of eco-friendly energy sources into businesses and homes will make Earth a better place to live. Students explore photovoltaics, the design behind wind turbine technology and the creative processes behind vehicles in the American Solar Car Race. Zero energy houses of the future will use many of these technologies to produce more energy than they consume. Renewable energy technologies are important for the future of our planet.
