For the nuclear energy: thorium and plutonium
Uranium is not lighter but heavier than many of the other elements; the density of uranium is 19,05 g/cm3 and the atomic weight is 238,02891.
Not uranium 239, but uranium 235 and plutonium 239.
Yes, uranium ores are available in many countries.
Uranium is an element and therefore by definition contains no chemical other than itself.
Polonium and radium are discovered in wastes from uranium minerals, after uranium separation. The important radioactivity of these residues (without uranium) warned the two about the possible existence of other radioactive elements.

There are many isotopes, especially of the trans-Uranium elements which can undergo nuclear fission. The isotopes which are used in nuclear reactors are Uranium-233, Uranium-235 and Plutonium-239, because these isotopes are more readily available than other fissionable isotopes. Uranium-235 occurs naturally, Uranium-233 can be made by neutron irradiation of Thorium-232 and Plutonium-239 can be made by neutron irradiation of Uranium-238.
Enriched uranium is an uranium with more than 0,7 % uranium 235.
Hydrogen is more available than uranium-235.
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
