What aspects of the composition of a nucleus can cause it to be unstable?
Wiki User
∙ 13y ago
The two aspects that cause the nucleus of any element atom to be unstable are:
- not have the specific neutron/proton ratio to be a stable nucleus, and or
- having number of protons that exceeds the stability limit (exceeding 83).
Referring to question below for more information.

Why are neutrons used as nuclear bullets to cause nuclear disintegration of an unstable nucleus?
Neutrons have no charge. As a result, they are not deflected by the positive charge of the nucleus or the negative charge of the electron cloud. They have the best chance of interacting with the nucleus and further destabilizing it, causing it to split.
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.
Which will NOT cause air to become unstable?
subsidence of an air column
Why fission cannot take place with fast neutron?
In order to cause an atomic nucleus to become unstable so that it will undergo fission, you have to add a neutron. If a slow neutron collides with an atomic nucleus, it will be absorbed into the nucleus and become part of it. The nuclear attraction of the nucleus is strong enough to grab a slow neutron. But a fast neutron cannot be captured because it has too much kinetic energy. The attraction of the nucleus is not enough to stop the motion of a fast neutron. Even if a fast neutron makes a direct hit on an atomic nucleus, it is just going to bounce off.
What agent of metamorphism can cause the overall composition of the rock to change?
hydrothermal solutions
What can cause a nucleus to become unstable and decay?
Too many or too few neutrons.
A free-moving neutron is absorbed by the nucleus of an atom. This can cause?
the atom to become unstable and rip apart

How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
What is the cause of genetics?
It is caused by a mutation in the gene called LMNA. The LMNA gene produces the Lamin A protein which holds the nucleus of a cell together. Researchers now believe that the defective lamin A protein makes the nucleus unstable. That cellular instability causes premature aging.

What does not cause air become unstable?
water
How does positron emission cause nuclear transmutation?
It is in beta plus decay that we see the positron emitted from the nucleus. (An electron is emitted in beta minus decay.) Within the nucleus of an unstable atom, a proton transforms into a neutron, and a positron is ejected from the nucleus (along with a neutrino). As the nucleus now has one more proton than it did before, its atomic number just went up by one; it is another element.
