What quality in uranium makes it useful in nuclear power?
An unstable nucleus which decays emitting a neutron.
When does Uranium-235 become unstable?
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.
What makes trans-uranium elements radioactive?
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
Is uranium an example of an unstable element?
All the isotopes of uranium (natural or artificial) are radioactive and unstable.
Is uranium stabled?
Uranium is unstable, radioactive element.
What is the number of protons in the nucleus of a uranium atom?
92 protons in uranium nucleus
What is a nuclear reaction?
One large nucleus, typically uranium, undergoes fission and releases several neutrons along with the major fission products. These neutrons strike more uranium atoms and are absorbed by the nucleus causing it to become unstable. It undergoes fission releasing more neutrons and more fission products. These neutrons strike more uranium atoms etc.
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium what happens next?
If things go according to plan, the neutron encounters a fissionable atomic nucleus and then undergoes what is called neutron capture. That's the next step in the process. The presence of that neutron in the nucleus destabilizes the nucleus (more than it already is as that nucleus is radioactive and unstable anyway). In an extremely short period of time the instability results in nuclear fission. The nucleus splits.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
How many protons does uranium have in its nucleus?
Uranium has 92 protons.
How do you unstable uranium?
you have to give it 6 valence electrons
Does uranium exist in a stable non-radioactive form?
All the isotopes of uranium are radioactive and unstable.
