Can uranium bond with other elements?
Uranium is a relatively reactive element. It combines with nonmetals such as oxygen, sulfur, chlorine, fluorine, phosphorus, and bromine. It also dissolves in acids and reacts with water.
Are most radioactive elements unstable?
All elements to element 94 are found in nature, and the remainder of the discovered elements are artificially produced, with isotopes all known to be highly radioactive with relatively short half-lives (see below)….Tables.

Which uranium isotope is unstable?
U-234
U-234 decays into Thorium-230 by alpha decay except for the tiny fraction of nuclei which undergoes spontaneous fission. Therefore, U-234 is an unstable isotope of Uranium.
Is uranium highly reactive?
Characteristics: Uranium is a dense, silvery-white, slightly paramagnetic, radioactive metal. Uranium is a highly reactive metal and reacts with almost of all the nonmetallic elements and many of their compounds. It dissolves in acids, but it is insoluble in alkalis.
Which element is most likely radioactive and unstable?
Many elements have one or more isotopes that are radioactive. These isotopes are called radioisotopes. An example of a radioisotope is carbon-14.
Why are uranium isotopes unstable?
The heat released in fission can be used to help generate electricity in power plants. Uranium-235 (U-235) is one of the isotopes that fissions easily. During fission, U-235 atoms absorb loose neutrons. This causes U-235 to become unstable and split into two light atoms called fission products.
Which element is the most unstable?
Francium
Characteristics. Francium is one of the most unstable of the naturally occurring elements: its longest-lived isotope, francium-223, has a half-life of only 22 minutes.
How do you know which element is more unstable?
So far we have made a couple of generalisations about the stability of isotopes:
- Elements with atomic number (Z) greater than 82 have no stable isotopes.
- Isotopes of elements with atomic number (Z) less than 20 are likely to be unstable if the neutron to proton ratio is either.
