New elements on the periodic table are named
Jul 05, 2016

  • The International Union of Pure and Applied Chemistry, which rules on chemical element names, presented its proposal for public review. The names had been submitted by the element discoverers.

  • The four elements, known now by their numbers, completed the seventh row of the periodic table when the chemistry organization verified their discoveries

  • Four elements are:
    Nihonium and symbol Nh, for the element 113,
    Moscovium and symbol Mc, for the element 115,
    Tennessine and symbol Ts, for the element 117, and
    Oganesson and symbol Og, for the element 118.

What is IUPAC:

  • The International Union of Pure and Applied Chemistry is an international federation of National Adhering Organizations that represents chemists in individual countries.

  • Its international headquarters of IUPAC is in Zürich, Switzerland.

  • IUPAC was established in 1919 as the successor of the International Congress of Applied Chemistry for the advancement of chemistry.

  • Before the creation of IUPAC (1919), a predecessor body, the International Association of Chemical Societies (IACS), had met in Paris in 1911 and produced a set of proposals for the work that the new Association should address.

  • IUPAC serves the international scientific endeavor in the dual function of a basic science and a mission-oriented Union. The Union is in a unique position to contribute to the central interdisciplinary chemical sciences.

What is periodic table:

  • The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties.

  • This ordering shows periodic trends, such as elements with similar behavior in the same column.

  •  It also shows four rectangularblocks with some approximately similar chemical properties.

  • Dmitri Mendeleev published in 1869 the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements
