What causes a nucleus to decay be unstable?
Too many neutrons or protons can upset this balance making the nucleus unstable. Nuclei with too many, or too few, neutrons do exist naturally but are unstable and will disintegrate (or decay) by emitting radiation. This is called radioactive decay.
What causes a nucleus to be unstable quizlet?
Too many neutrons or protons can cause a nucleus to become unstable and decay. Nuclei with more than 83 protons are always unstable. a series of fission processes in which the neutrons emitted by a dividing nucleus cause the division of other nuclei.
Which process describes the release of particles by an unstable nucleus?
Radioactivity is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation, As each nucleus disintegrates, in its effort to find a more stable combination, it emits a charged particle that, because of its kinetic energy, is capable of penetrating solid material.
Why do very large nuclei tend to be unstable?
Greater number of protons and neutrons render the nucleus and thus atom unstable. Not all the nuclei but the larger nuclei usually are unstable containing greater number of protons and neutrons.
What causes the instability of an atom’s nucleus?
Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
How do you determine the stability of a nucleus?
Ernest Z. The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in the nucleus. The principal factor for determining whether a nucleus is stable is the neutron to proton ratio. The graph below is a plot of the number of neutrons versus the number of protons in various stable isotopes.
What are the factors that affect the stability of nuclear elements?
Nuclear Stability 1 Nuclear forces. 2 Mass defect and binding energy. 3 The neutron to proton ratio (N/Z ratio). 4 Odd and even number of nucleons.
How do odd and even numbers of protons affect nuclear stability?
Nuclides contain odd numbers of protons and even numbers of neutrons are less stable than nuclides containing even numbers of protons and odd numbers of neutrons. In general, nuclear stability is greater for nuclides containing even numbers of protons and neutrons or both.
