Scientists are trying to fabricate heavy elements through fusion. One element that they have not yet been able to make would have an atomic number of 120 and would be positioned in column 2A on the periodic table directly below Ra. Based on observed patterns, scientists have already predicted how this element might behave. In the next three questions, you are asked to use your understanding of chemistry to make some predictions of your own.
