if an atom with atomic number 119 were to be discovered, the naming process would follow the guidelines set by the International Union of Pure and Applied Chemistry (IUPAC).
According to the current IUPAC guidelines, new elements are typically named after a mythological concept, a mineral, a place, a scientist, or a property of the element. The final decision on the element's name would be made by the discoverers and be subject to approval by the IUPAC.
In the case of an atom with atomic number 119, since it is a hypothetical scenario, I cannot provide a specific name for it. However, it would likely follow the naming conventions established for new elements.
It's worth noting that the highest atomic number element that has been officially named is element 118, which is called oganesson (Og). If any new elements have been discovered beyond that point, their names and properties may not be known to me. I would recommend checking reputable scientific sources or recent literature for the most up-to-date information on new element discoveries and their names.
