Tboom for Ytterbium, Yb,
Tboom=338.632∗173.04∗10−32∗8.3144=1193.26K or 920.11oC
and
Tboom for Uranium, U,
Tboom=713.222∗238.028∗10−32∗8.3144=7281.38K or 7008.23oC
Ytterbium melted at Tboom=1193.26K, as its melting point is at 1097K. Uranium is superheated at Tboom=7281.38K, because it boils at 4404K.
Tboom is boring...
