“Our question⟳ at the beginning of this essay was "are there more elements to be discovered?" The next elements would be ununennium (atomic number⟳ 119) and unbinilium (atomic number⟳ 120). The problems in trying to produce⟳ these elements by accelerating an ion beam into a target⟳ are the short half-lives of possible target⟳ elements and the extended times required for a successful observation of a new element. So far, elements 119 and 120 have⟳ eluded discovery. But you can expect⟳ that scientists will continue⟳ to search⟳ for new elements.”
