Question

What is the IUPAC name and symbol of elements with atomic number 120 ?

Answer 1

Hint: The International Union of Pure and Applied Chemistry's (IUPAC) nomenclature of organic chemistry is a technique of naming organic chemical compounds recommended[1] by the International Union of Pure and Applied Chemistry (IUPAC). It's in the Nomenclature of Organic Chemistry (informally called the Blue Book). Ideally, every potential organic molecule should have a name that can be used to generate an unambiguous structural formula. Inorganic chemistry has its own IUPAC nomenclature.

Complete answer:
The IUPAC name for atomic number 120 is Unbinilium and the symbol is Ubn. Unbinilium, also known as eka-radium or simply element 120, is a hypothetical chemical element with the symbol Ubn and atomic number 120 in the periodic table. The provisional systematic IUPAC names and symbols are unbinilium and Ubn, which are used until the element is identified, confirmed, and a permanent name is chosen. It is projected to be an s-block element, an alkaline earth metal, and the second element in the eighth period, according to the periodic table of the elements. It has drawn interest due to some forecasts that it may be in the island of stability, while subsequent calculations suggest that the island will occur at a somewhat lower atomic number, closer to copernicium and flerovium. Despite several attempts by German and Russian teams, unbinilium has yet to be synthesized. The experimental data from these attempts indicates that the period 8 elements would be significantly more difficult to synthesize than the previously known elements, and that unbinilium may be the last element that can be synthesized with existing technology.

Note:
Because unbinilium is the seventh alkaline earth metal, it should have properties similar to its lighter congeners; nevertheless, relativistic effects may cause some of its properties to diverge from those expected from a straight application of periodic trends.
