All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive.
Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay.
radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
Yes, uranium is an element. It is a naturally occurring radioactive metal with the symbol U and atomic number 92.
Uranium is a radioactive element; the isotope 235 is fissile with thermal neutrons; the isotope 238 is not so fissile but is fertile (transformation in the fissile isotope plutonium 239). Consequently, uranium is a good nuclear fuel and also can be used in nuclear weapons.
Uranium is a metallic element and is not classified as an acid or a base. It is a radioactive element that can be found in nature as uranium-238 and uranium-235 isotopes.
Uranium is a natural chemical element, solid, radioactive, unstable, having a great density, also atomic weight, with moderated reactivity, toxic, useful etc.
Uranium is an example of an actinde; also uranium is a solid metal, radioactive, a natural chemical element.
An example is uranium.
Yes, uranium is a radioactive element.
All the isotopes of uranium (natural or artificial) are radioactive and unstable.
Yes, uranium is a natural but radioactive element.
Uranium is unstable, radioactive element.
Uranium ia a radioactive and toxic element.
Radioactivity is discovered on uranium.
Uranium is a natural chemical element, metal, solid, radioactive, toxic, in the actinoids group, heavy atomic weight, high density.
Probably uranium is the best known radioactive element.
Uranium is a natural chemical element, situated in the actinides group; uranium is a solid metal, radioactive.
All the isotopes of uranium are radioactive and unstable.
