The Wikipedia entry for uranium describes it as 'malleable and ductile'. This seems the opposite of fragile. Considering that depleted uranium is used in armor piercing munitions, this does not indicate a fragile material.
Perhaps the "idea" behind the question relates to the fact that uranium is a fairly reactive metal. It's actually pyrophoric, meaning that when it is finely diveded, it will react spontaneously. If we could throw a spoonful of uranium powder into the air, it would react and burn in that air. This would not be smart, of course. It would, in fact, be a disasterously foolish thing to do as the resulting uranium compounds would pose a serious health risk. This is because uranium, though mildly radioactively, is a seriously toxic heavy metal. The combustion products would be airborne, and if inhaled, woe be unto the person who breathed much of it in.
The comparative form of "fragile" is "more fragile."
Fragile
FRAGILE
uranyl nitrate, uranium chloride, uranium tetrafluoride, uranium hexafluoride, uranium dioxide, uranium octaoxide, uranyl acetate, uranyl sulfate, uranyl oxalate, uranium carbide, uranium nitride, uranium sulfide, uranium sulfate, uranium selenide, etc.
A situation that is near to being imbalanced is fragile. A person who gets easily sick is fragile. A glass that is easily broken is fragile and the rain forest is about to become imbalanced so it is fragile.
Examples:Oxides: uranium dioxide, uranium trioxide, uranium octaoxideSalts: ammonium diuranate, uranyl nitrate, uranyl acetate, uranium hehxafluoride, uranium chlorideand many others because uranium is a reactive metal.
uranyl nitrate, uranium dioxide, uranium octaoxide, uranium hexafluoride, uranyl acetate, uranium tetrachloride, uranium carbide, uranium nitride, uranium tetraiodide, uranium sulfide, ammonium diuranate, etc.

Some examples of uranium compounds are: uranyl nitrate, uranium dioxide, uranium hexafluoride, uranium tetrachloride, triuraniumoctaoxide, uranyl acetate, uranium iodide, uranium nitride, uranium, sulfide, uranium carbide, uranyl sulfate, etc.
yes they are very fragile
most fragile
Yes, the nuclear fuel from a nuclear reactor must be replaced at some intervals, because the fuel can be poisoned with neutron absorbers and the clad can become fragile and unsure; the "burned" fuel is recycled.
