What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
What makes a fission reaction possible is that certain atoms are stable unstable energetic very small?
What makes a fission reaction possible is that certain atoms, such as uranium and plutonium, are unstable and capable of splitting into smaller atoms when struck by a neutron. This process releases a large amount of energy in the form of heat and additional neutrons, which can go on to trigger more fission reactions in a chain reaction.
What is the difference between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
What are the key differences between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
Atoms located above the band of stability on a graph of numbers of nuetrons versus number of protons are usually unstable because they contain too many what?
Neutrons. Atoms located above the band of stability have an excess of neutrons compared to protons, which makes them relatively unstable. This imbalance in the ratio of neutrons to protons can lead to radioactive decay in an attempt to reach a more stable configuration.
What is the process which describes the splitting of a large unstable atom into two intermediate size atoms and extra neutrons called?
Nuclear fission
The process by which describe the splitting of a large unstable atom into two intermediate size atoms and extra neutrons is called?
Fission to be more specific its nuclear fission...
What is the process of a neutron splitting a nucleus into two parts?
Neutrons do not split nuclei directly. However, when a neutron collides with a nucleus, it can be absorbed, causing the nucleus to become unstable. This instability can result in the nucleus splitting into two smaller nuclei, a process known as nuclear fission. During fission, energy, more neutrons, and radiation are released.
Does too many neutrons determine if an isotope is unstable?
An isotope with too many neutrons can be unstable for example Hydrogen-3 is unstable while hydrogen-1 and 2 are stable. But so can one with too few neutrons, for example lead-204 is unstable while lead-206, 207, and 208 are stable.
What are examples of isotopes with fewer neutrons than protons?
Hydrogen-1 (protium):1 proton, 0 neutrons (stable) Helium-2 (diproton): 2 protons, 0 neutrons (unstable - short half-life) Helium-3: 2 protons, 1 neutron (stable) Lithium-4: 3 protons, 1 neutron (unstable - extremely short half-life) Lithium-5: 3 protons, 2 neutrons (unstable - extremely short half-life) Beryllium-5: 4 protons, 1 neutron (mostly theoretical, unstable, extremely short half-life if formed) Beryllium-5: 4 protons, 2 neutron (unstable - extremely short half-life) Beryllium-5: 4 protons, 3 neutron (unstable - extremely short half-life) Boron-6: 5 protons, 1 neutron (mostly theoretical, extremely short half-life if formed) Boron-7: 5 protons, 2 neutron (unstable - extremely short half-life) Boron-8: 5 protons, 3 neutron (unstable - short half-life) Boron-9: 5 protons, 4 neutron (unstable - extremely short half-life) Carbon-8: 6 protons, 2 neutrons (unstable - extremely short half-life) Carbon-9: 6 protons, 3 neutrons (unstable - short half-life) Carbon-10: 6 protons, 4 neutrons (unstable - short half-life) Carbon-11: 6 protons, 5 neutrons (unstable - short half-life) Nitrogen-10: 7 protons, 3 neutrons (unstable - extremely short half-life) Nitrogen-11: 7 protons, 4 neutrons (unstable - extremely short half-life) Nitrogen-12: 7 protons, 5 neutrons (unstable - short half-life) Nitrogen-13: 7 protons, 6 neutrons (unstable - short half-life) Oxygen-12: 8 protons, 4 neutrons (unstable - extremely short half-life) Oxygen-13: 8 protons, 5 neutrons (unstable - extremely short half-life) Oxygen-14: 8 protons, 6 neutrons (unstable - short half-life) Oxygen-15: 8 protons, 7 neutrons (unstable - short half-life) Fluorine-14: 9 protons, 5 neutrons (unstable - extremely short half-life) Fluorine-15: 9 protons, 6 neutrons (unstable - extremely short half-life) Fluorine-16: 9 protons, 7 neutrons (unstable - extremely short half-life) Fluorine-17: 9 protons, 8 neutrons (unstable - short half-life) Neon-16: 10 protons, 6 neutrons (unstable - extremely short half-life) Neon-17: 10 protons, 7 neutrons (unstable - extremely short half-life) Neon-18: 10 protons, 8 neutrons (unstable - short half-life) Neon-19: 10 protons, 9 neutrons (unstable - short half-life) ... and the list goes on
What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
What has role in neutrons changing into protons and electrons into unstable atoms?
strong force
What is an intermediate in the reaction?
an unstable structure formed during the process of reactiom and is later converted to products
Why is mercury-194 the unstable one I thought it was molybdenum-98 since the neutrons are LESS than protons and therefore don't balance out the strong/electric force between protons and neutrons. How do you determine which isotopes are unstable?
yes
What are the primary factor determining whether or not an atom is stable or unstable?
I, too, also had this questions. After SEVERAL minutes of surfing the world wide web, I found that it is the number of neutrons that determine whether a nucleus is stable or unstable. I hope this helps you! ;)
