What does uranium look like?

Uranium is a dense, silvery-white metal that is weakly radioactive. In its natural state, it has a metallic luster and can also appear as a black oxide when exposed to air. It is primarily used in nuclear reactors and weapons.

Why only radioactive element give out radiation?

It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.


Can you eat radiation?

Well you could eat uranium or other or radioactive waste... But as Uranium is expensive and rare, and radioactive waste is deadly, eating radiation would result in killing you. This will not give you super powers like shown in cartoons, but it will end up with you receiving radiation poisoning.


An element that gives off nuclear radiation what?

Sounds to me like radiation from a radioactive isotope. The breaking down part would be the half-life. But the isotope won't completely break down. Only until it reaches a stable form. Such as, radium-226 decays finally to lead-206. During the process it emits charged Alpha particles.

What elements give off particles?

the unstable elements in periodic table is Radium because it always leave the radio active waves so it lost its mass slowly slowly all radio active elements are unstable. Any thing more By Varun


Does quartz give off radiation?

Quartz itself does not give off radiation. However, certain impurities or inclusions within quartz crystals can make them weakly radioactive. These radioactive elements include uranium, thorium, and potassium.


Gamma ray sources of the radiation?

Various radioactive substances such as Plutonium and Uranium give off a combination of alpha, beta and gamma rays as the isotope decays.


What elements give off small particles?

Elements that can give off small particles include radioactive elements like uranium and radium, as well as elements in the form of nanoparticles such as gold, silver, and iron. These small particles can be released into the environment through processes like radioactive decay or as byproducts of industrial activities.
