3. Atomic Number- 92 Atomic Mass- 238.03 Classification- Rare Earth Number of Protons/Electrons- 92 Number of Neutrons- 146 Date of Discovery- 1789 Discoverer- Martin Klaproth Name Origin- Planet Uranus 1 st Ionization Energy- 584 kJ/mole Heat of fusion- 8.520 kJ/mol Can be found in- igneous rocks

4. Uranium is extremely hot Extreme radiation its got Causes death by the pounds Its found in a lot of rock mounds Its used for nuclear fuels But its temperature doesn’t get cool In 1789 I was discovered by Martin Klaproth He of course found it in an igneous rock Its used for inertial guidance devices Its radiation is going to cause a crisis Its classification is rare earth The beginning of time is the time of its birth
