Great quiz! Can't believe I forgot about noble gases being here too, and then trying to remember the gases and nonmetals near them... still got 100% though!
"going down group 17, the metallicity of the elements increases; for example, iodine already exhibits a metallic luster in the solid state, and astatine is expected to be a metal. As such, an extrapolation based on periodic trends would predict tennessine to be a rather volatile metal."
