Using specific elements, give a brief explanation for how scientists could possibly create a new element with the atomic number 120. What family would this probably be placed in? What would you name it and why?

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms
