Let’s learn about LUTETIUM!

      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. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. Lutetium is generally considered the first element of the 6th-period transition metals by those who study the […]

Let’s learn about GERMANIUM!

                                    Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. […]

Let’s learn about ARSENIC!

                                    Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is […]

Let’s learn about CERIUM!

                                    Cerium is a chemical element with the symbol Ce and atomic number 58. Cerium is soft, pliable, and silvery-white metal that discolors and ruins when exposed to air, and it is soft enough to be cut with […]

Let’s learn about OGANESSON!

      Oganesson is a (produced by people/not naturally-occurring) chemical element with the symbol Og and atomic number 118. It was first made/created in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow, Russia, by a combined team of Russian and American scientists. In December 2015, it was recognized as […]

Let’s learn about YTTERBIUM!

      Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and next-to-the-last element in the lanthanide series, which is the basis of the relative (firm and steady nature/lasting nature/strength) of its +2 oxidation state. However, like the other lanthanides, its most common oxidation state is […]

Let’s learn about DUBNIUM!

      Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. This greatly limits extended research on dubnium. Dubnium does not occur naturally on Earth and is produced artificially. The Soviet Joint […]

Let’s learn about TERBIUM!

      Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is bendable, (able to be flattened or drawn into wire), and soft enough to be cut with a knife. The ninth member of the lanthanide series, terbium is a fairly electropositive […]
