Let’s learn about XENON!

      Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth’s atmosphere in trace amounts. Although generally unreactive, xenon can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be […]

Let’s learn about TELLURIUM!

    Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals. Tellurium is far more common in the […]

Let’s learn about POLONIUM!

      Polonium is a chemical element with the symbol Po and atomic number 84. Polonium is a chalcogen. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and […]

Let’s learn about BISMUTH!

Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% […]

Let’s learn about CAESIUM!

  Caesium is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature.  It has physical and chemical properties similar to […]

Let’s learn about RUBIDIUM!

  Rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. It is the second most reactive metal. Rubidium is the chemical element with the symbol Rb and atomic number 37. It is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium […]

Let’s learn about MAGNESIUM!

    Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and […]

Let’s learn about HYDROGEN!

  Hydrogen (H) is a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The H atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; an electron, bearing one unit of negative electrical charge, is also associated with this nucleus. Under […]

Let’s Learn About BERYLLIUM!

  Beryllium is a silvery-white metal. It is relatively soft and has a low density. Named after beryllos, the Greek name for the mineral beryl, the element was originally known as glucinium — from Greek glykys, meaning “sweet” — to reflect its characteristic taste. But the chemists who discovered this unique property of beryllium also […]

Let’s Learn About TUNGSTEN!

  Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost only as compounds with other elements. It was identified as a new element in 1781 and first (separated far from others) as a metal in 1783. Its important ores […]
