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.

Enriched uranium is an uranium with more than 0,7 % uranium 235.
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
Often uranium dioxide is used as fuel in nuclear power plants either as UOX (uranium dioxide) or MOX (mixed oxides, typically uranium and plutonium). There are a number of other fuel types, however, and not all plants use uranium dioxide. The other fuel types include metal alloys, ceramics, and various chemical compounds other than oxides.
Uranium combine with the majority of other elements; also uranium has alloys with the majority of metals.
