What Is A Stable Proton To Neutron Ratio? Their stability is determined by the ratio of the number of neutrons to the number of protons in the nucleus. At low atomic masses, the stable ratio is approximately 1:1. At about an atomic mass number of 20 this starts to increase until it is around 1.5:1
Which Element Is Chemically Stable? The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable. What is the most stable
Is Neutron A Stable Particle? Without a source for this additional energy the neutron cannot decay. Hence the neutron in a deuteron is stable. … The decay of free neutrons is energy feasible because the mass of a neutron is greater than the sum of the masses of the proton and electron it decays into.
What Does It Mean When A Nucleus Is Stable? Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. … Note that a few radioactive atoms have lifetimes longer than the age of the Universe (e.g., 209Bi), while others become stable when
What Is The Least Stable Nucleus? Hence the radioactivity is associated with unstable nucleus. Nuclides with odd number of protons and neutrons are the least stable infers more radioactive. Nuclides with even numbers of both protons and neutrons are most stable infers less radioactive. Which of the following nuclear is least stable? Nuclides containing odd
