Study with Quizlet and memorize flashcards containing terms like What does the nuclear stability curve show?, What is the ratio in the blue band?, What are isotopes if they lie off the blue band? and more.
At a short range (around 1–3 fm), nucleons are bound by the strong nuclear force. Below 1 fm, the strong nuclear force is repulsive in order to prevent the nucleus from collapsing. At longer ranges, the electromagnetic force acts between protons, so more protons cause more instability.
29 Ιουλ 2023 · All the stable nuclei lie within a definite area called the zone of stability. For low atomic numbers most stable nuclei have a neutron/proton ratio which is very close to 1. As the atomic number increases, the zone of stability corresponds to a gradually increasing neutron/proton ratio.
Nuclear Stability is a concept that helps to identify the stability of an isotope. To identify the stability of an isotope, it is needed to find the ratio of neutrons to protons. To determine the stability of an isotope, you can use the ratio neutron/proton (N/Z).
Nuclear Stability — Definition & Overview A stable nucleus will not spontaneously decay. Nuclear stability depends on the composition of the nucleus and its attractive and repulsive forces.
Definition. Nuclear stability refers to the ability of an atomic nucleus to maintain its structure over time without undergoing radioactive decay. A stable nucleus has a balanced ratio of protons and neutrons, which minimizes the forces that could lead to instability.
