All the isotopes of uranium (natural or artificial) are radioactive and unstable.
Uranium is unstable, radioactive element.
Through radioactive decay, because Uranium (element 92) is unstable.
none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.
Uranium is considered a radioactive chemical element because uranium (all the isotopes) is unstable and emit nuclear radiations.
Uranium is an example of an actinde; also uranium is a solid metal, radioactive, a natural chemical element.
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
All the isotopes of uranium are radioactive and unstable.
An example is uranium.
Uranium is a natural chemical element, solid, radioactive, unstable, having a great density, also atomic weight, with moderated reactivity, toxic, useful etc.
Uranium is radioactive because it is an unstable element with a nucleus that can undergo radioactive decay. During this decay process, uranium releases energy in the form of alpha, beta, or gamma radiation as it transforms into other elements over time. This radioactive decay is what makes uranium useful for nuclear energy and weapons.
A disintegration series is the pathway of a radioactively unstable element into a stable element. The pathway alters the atomic number of the element and converts the element into another element. A common one is the uranium disintegration series.
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.
