Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
What makes a nucleus radioactive?
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
In nuclear fission reactions what causes the atom's nucleus to become unstable?
the absorption of a free-moving neutron by the atom's nucleus
What happens to the nucleus when a neutron hits it?
When a neutron hits the nucleus, it can be absorbed by the nucleus, causing the nucleus to become unstable and possibly undergo radioactive decay. This process can lead to the release of energy, emission of radiation, or transmutation of the nucleus into a different element.
What is the name of a large atom?
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
What quality in uranium makes it useful in nuclear power?
An unstable nucleus which decays emitting a neutron.
What makes a nucleus unstabe?
A nucleus with too few nuetrons is unstable because there are not enough to keep the protons. There must be a certain amount of nuetrons for every element.
What makes an element unstable or radioactive?
The stability of an atom depends on a balance between the numbers of protons and neutrons in its nucleus and also on the total size of its nucleus; atoms with sufficiently large nuclei are inherently unstable. Please see the link.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What makes trans-uranium elements radioactive?
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
What is the term for an atom that has an unstable nucleus?
radioisotope
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
What is natural transmutation?
Change from unstable to stable nucleus.
Is radioactivity caused due to unstable nucleus?
Yes.
What makes a atom unstable?
it might not be unstable with anything.......
