"The names still have to go through after a five-month public comment period," and are set to be written into the table officially in May. The public is invited to discuss what to name both elements, so consider the current names "placeholders," says Alan Boyle at MSNBC. Other groups with specific names are the pnictogens (group 15), chalcogens (group 16), halogens (group 17), and the noble gases (group 18, also known as inert.

An interactive, printable extended version of the Periodic table of chemical elements of Mendeleev (who invented the periodic table). Use this Excel periodic table template to learn about elemental and chemical properties, explore compounds, view and compare structure diagrams, and more. Livermorium was named after the city of Livermore, Calif., where it was created. Naming an element is an "arduous" process, says Kenneth Chang at The New York Times. The current names are merely proposals put forth by the International Union of Pure and Applied Chemistry, "the scientific body that is the keeper of the list of elements." The union has "finicky rules about what it considers an acceptable name." For instance, if a previously proposed element's name is rejected, that name cannot be proposed for any "subsequent element discoveries." How did the new elements get their names? The elements were first synthesized over 10 years ago, but it was only recently - and through repeated experiments - that their existence was finally confirmed. Chemical Elements on the Periodic Table 2022 Subject: Chemistry Size: LARGE A2 Wall Chart Good educational tool for Parents, Teachers, Tutors & Students Ideal for revision / memory aid for Schools & Colleges Dimensions: Metric: 420 x 594mm Imperial: 16.5 x. Known as "super heavy" or "Transuranium" elements, "they fall apart into other elements very quickly," so scientists haven't been able to study their potential applications quite yet. Numbers 114 and 116 will sit "down in the lower-right corner of the periodic table." In real life, both elements are "so large and unstable" that they can only be created in a lab, says Jennifer Welsh at Live Science.
