Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.

∙ 13y agoUranium 238 is a radioactive non-stable isotope. Uranium 238 is the most stable out of the other uranium isotopes as it takes millions of years to complete radioactive decay when the other uranium isotopes take days or minutes. No uranium isotope is stable, that is what makes it a radioactive element.

A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.

subsidence of an air column
What is true about the fission of uranium235?
The reaction produces more neutrons than were needed to start it.
When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when the forces in the nucleus are balanced, until they become stable.
