4 new elements added to the periodic table

The periodic table, a tabular arrangement of various chemical elements, has just got a new look as four new elements have been added to its seventh row. The International Union of Pure & Applied Chemistry has confirmed that it has officially added four new elements, with numbers 113, 115, 117 and 118, to the table. These elements will no longer be known by their placeholder names; instead they will have all-new monikers determined by their discoverers.

The four new elements are: Nihonium (element 113), Moscovium (element 115), Tennessine (element 117) and Oganesson (element 118).

Nihonium (Nh) is named for the Japanese word for Japan, which is Nihon; which Moscovium (Mc), Tennessine (Tn) and Oganesson (Og) have been named for Moscow, Tennessee and 83-year-old physicist Yuri Oganessian, respectively.

Prof. Natalia Tarasova, the president of IUPAC, "Universality of science, honoring places from three continents, where the elements have been discovered - Japan, Russia, the United States - and the pivotal role of human capital in the development of science, honoring an outstanding scientist - Professor Yuri Oganessian."

The table shows chemical elements in a tabular arrangement, ordered by their atomic number, electron configurations as well as their recurring chemical properties. The ordering of the chemical elements shows periodic trends. For instance, chemical elements with similar behavior are placed in the same column. With row seven of the periodic table now completed, chemists around the globe will likely start looking to the road ahead, with a hope to discover entirely new elements.
