Calcium is a chemical element with the symbol Ca and atomic number 20. It is an alkaline earth metal.
Barium is a chemical element with the symbol Ba and atomic number 56. It is a soft, silvery alkaline earth metal.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive alkali metal.
Tin is a chemical element with the symbol Sn and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue.
Samarium is a chemical element with the symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air.
Lead is a chemical element with the symbol Pb and atomic number 82. It is a heavy metal that is denser than most common materials.
Polonium is a chemical element with the symbol Po and atomic number 84. It is a rare and highly radioactive metal with no stable isotopes.
Mendelvium is a radioactive metal of the actinide series. It does not occur naturally and was first made in 1955 by bombarding einsteinium with helium ions.
Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.
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.
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.
