The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which ge...
The International Union of Pure and Applied Chemistry (IUPAC) confirmed the names of elements 113, 115, 117, and 118 as: Nihonium(symbol Nh), for element 113 Moscovium(symbol Mc), for element 115 Tennessine(symbol Ts), for element 117 ...
Finally, in 1869, the German Lothar Meyer and the Russian chemist Dmitry Ivanovich Mendeleev almost simultaneously developed the first periodic table, arranging the elements by mass. However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the ...
Elements—UpdatedReleaseAn updated version of the Periodic Table has been released on 28 November 2016 which includes the recently added elements 113, 115, 117, and 118 and all standard and conventional atomic weights.doi:10.1515/ci-2017-0108Hyun Jung Gu...

Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by vario...
When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. ...
