Yes, uranium is oxidized in air even at room temperature (surface oxidation) but at high temperature the oxidation is total; the formed oxide is U3O8.

Is uranium toxic?
technically. uranium emits radiation which is harmless if we don't absorb to much of it but too much and we either die or our offspring and/or we have genetic mutationsAnother answer:You should avoid Uranium. In addition to being weakly radioactive, Uranium IS a toxic metal. Normal functioning of the kidney, brain, liver, heart and other systems can be affected by uranium exposure. Uranium is also a reproductive toxicant. Exposure to uranium and its decay products, especially radon, are widely known.Also note that finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature.
Is uranium a form of chemical energy?
No, since uranium in a radioactive element, it stores Nuclear energy.Actually metallic uranium stores lots of chemical energy and can burn violently. Finely divided metallic uranium is even pyrophoric (it will ignite on exposure to air).
Is uranium reflective?
A freshly cut surface on uranium is silvery white and quite reflective, but in air uranium oxidizes very rapidly and in minutes this surface will become tarnished with a black uranium oxide coating.
What color is uranium in its liquid state?
Uranium is a silvery-grey metal in both solid and liquid state, However on exposure to air it produces a black uranium oxide on its surface, which would happen much faster to liquid uranium than to solid uranium.
What do you mix with cornstarch to get it to ignite?
Cornstarch dispersed through a pvc pipe with compressed air over a heat source will ignite. I wouldn't try this on a windy day. Be safe and responsible!
What is the safety isuse for uranium 235?
It's radioactive. It causes many different cancers and other ailments. And the most fun one...uranium dust is flammable, and it will ignite spontaneously in air, a property called "pyrophoricity."

Does uranium cause an air pollution?
Yes, uranium mining and uranium industry can cause air pollution with uranium aerosols; also the decay chain products radium and radon (gas) are dangerous. Severe precautions were taken when working with uranium.
How does uranium react with oxygen?
Uranium produces several oxides. It corrodes in air.
Why is phosphurous stored in water?
Because it can spontaneously ignite in air.
What is the difference between LEL and UEL?
LEL is the Lower Explosive Limit. The lowest ignitable concentration of a substance in air that will ignite. UEL is the Upper Explosive Limit. The highest percentage of a substance in air that will ignite.
Does uranium have little air pollution?
The air pollution with uranium is generally not important (excepting the area of mines); but the radioactive gas radon, a product of the radioactive decay chain of uranium is very dangerous and responsible for some lung cancers.
Is Uranium found in air water or earth?
in earth
What is the purpose of the spark plug?
It ignites the compressed air/fuel mixture.
Why do you need to bleed a diesel?
Diesel engines work in a different way to petrol in that they work on pressure to ignite warm diesel as opposed to petrol engines which have spark plugs. in order to work, there can be no air, air wont ignite!!
