Why did the nucleus stay together when we added two neutrons?
The nucleus of an atom is held together by the strong nuclear force that binds together protons and neutrons. Although the strong nuclear force is the strongest of the four fundamental forces, it acts only over very short – typically nuclear – distances. It binds together the protons and neutrons in the nucleus.
How positively charged protons can stay together in a nucleus quizlet?
Strong nuclear force in an atom is an attraction of positively charged protons in the nucleus that remain clumped together. It acts between all nucleons. So long as the attractive strong nuclear force is stronger than the repulsive electric force, the protons will remain together.
What keeps the protons in an atomic nucleus from flying away from one another quizlet?
Positive electric charges repel each other, so why do the protons that are part of a nucleus not push each other away? The strong force is the force that causes protons and protons as well as protons and neutrons to be attracted to each other.
What keeps the electrons and protons attracted to each other?
Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still. Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron.
What nucleus has the highest binding energy?
nickel-62
Which element has more binding energy?
Iron 56
Why does iron have the most stable nucleus?
This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. It is most efficiently bound and has the lowest average mass per nucleon. It takes more energy per nucleon to take one of these nuclei completely apart than it takes for any other nucleus.
Which particle is bombarded on heavy nucleus of nuclear fuel?
Explanation: Nuclear fission involvs bombardment of certain particles on heavy nucleus causing it to split. All modern fission reactors uses neutron particles for this purpose because they are neutral in charge and so, they can make their way through the shells of electrons and then through the nucleus at low energy.
How does alpha radiation affect the body?
Inside the body, however, they can be very harmful. If alpha-emitters are inhaled, swallowed, or get into the body through a cut, the alpha particles can damage sensitive living tissue. The way these large, heavy particles cause damage makes them more dangerous than other types of radiation.
