The periodic table of the chemical elements is a fundamental tool that has made modern chemical science possible.  In the past few decades several elements have been discovered and added to the periodic table, and in 2015 the names and atomic symbols of four new elements were announced, completing the bottom, seventh row of the table.  The United Nations has declared 2019 the International Year of the Periodic Table, and students and the public love to learn about new elements and even to suggest names and symbols for them.  Laboratories around the world carry out the research that leads to discoveries of new elements, and a careful and a meticulous process is followed by the International Union of Pure and Applied Chemistry, IUPAC, and the International Union of Pure and Applied Physics, IUPAP, to verify claims of discovery of new elements and to recommend names and atomic symbols for them.  In this talk the processes of research, discovery, verification and naming of new elements will be described.<br/>
