According to the Star Trek Fifth Interstellar Geophysical Conference Standard version of the periodic table, there are 140 known elements. In what group of the periodic table would you place element 117, "topaline," which is reported to have been discovered on Ganymede in 2021? Group If the symbol for topaline is To, predict the formula of a compound that would presumably result from the reaction between barium and topaline, and name the compound. Spelling counts formula name:
