Binding energy Definition and 251 Threads

Hello, I don't know whether this is more appropriate forum than the astrophysics as far as the black holes are conserned... Anyway I would like to know what happens to the binding energy when a black hole eats an object? It is necessary to radiate it in order the object would not escape...

The problem is this: Estimate the binding energy of the H2 molecule, assuming the two H nuclei are 0.074 nm apart and the two electrons spend 33% of their time midway between them. I assume that this problem uses the equation F=ke2/d. So far, I have that E1=F1d, and E2=F2v*t*0.33. Then...

Homework Statement Calculate the binding energy of a neutron in 13-C. Homework Equations mass defect= (Z*mp) + (N*mn) - (mc13) B = mass defect * conversion factor B/(Z+N) = Binding Energy per Neutron I wasn't given any values for the numbers, so I wiki'd them. The Attempt at a...

As I understand it, in all forms of radioactive decay, constrained by E=mc^2, a spontaneous breakdown of an element or isotope occurs: that is, a massive element (parent) decays to a less massive element, isotope or leptons [daughter(s)], plus a release of energy. However, in alpha decay, the...

I've got a question on nuclear physics, specifically binding energy. I understand that binding energy is the energy needed to separate a nucleus into its constituents. But something has been bugging me. For example, Two deuterium nuclei fuse together to form a Helium-3 nucleus, with the...

The buildup of heavier elements in the nuclear fusion processes in stars is limited to elements below iron, since the fusion of iron would subtract energy rather than provide it The fusion of two nuclei lighter than iron generally releases energy while the fusion of nuclei heavier than...

How does the binding energy per nucleon of a nucleus affect its stability?

I'm doing a nuclear chemistry project right now, and I am able to solve all of the problems involving binding energy and mass defect, however I have one conceptual question. Why is it that when the nucleons combine with each other they let off energy? At first I thought it was their kinetic...

Hi My teacher told me that its because of binding energy that we and everything around us exist. I have presented this viewpoint in my blog: http://hubpages.com/hub/The-energy-responsible-for-our-existence---BINDING-ENERGY" Please visit it and give comments. If you find mistakes please...

I am a little bit confused. If U235 decays 2 neutrons, and the two daughter atoms posses a larger amount of binding energy per nucleon, then why is there excess energy? Why doesn't this process require the input of additional energy? I know I am missing something fairly simple.

Hi there all, I'm new at this whole idea of using a forum, but am unfortunately stuck on some of the theory behind my high school nuclear physics teaching. Basically its to do with the mass deficit and E=mc^2. We have learned so far that the uncombined nucleons of an atom have more mass than...

The following question deals with planetary motion: energy totals and binding energy. I have solved the question to the best of my ability, but I cannot get the right answer! I don't know what I am doing wrong, and would greatly appreciate it if someone could point out my mistakes. Homework...

I am aware that quarks can not be separated due to the strong force growing with distance. My question is, instead of pulling them apart can you "remove" the energy between them and therefore separate them. There are two ways I have thought about this. One, the technological question of can...

We know that induvidual nucleons are heavier than the nucleus. So Nucleons should have more gravitational potential energy with respect to the rest of the universe than the nucleus. Doesn't this violate the law of conservation of energy ?

I was just doing a little test and one question that I got wrong and can't seem to rationalise the supposed correct in a satisfactory way involved gamma decay and binding energy. What it basically asked was, if gamma decay occurs, and hence energy is released, how is the binding energy per...

The energy that binds an orbiting electron to the hydrogen nucleus is 13.4 eV. Calculate the ratio of the binding energy per nucleon to the binding energy per electron in deuterium. Which part is held more tightly, the electron or the neutron? I already worked out the average binding energy...

Can someone explain the difference to me? Is it correct that the binding energy is the energy needed to bring an electron to the fermi level, and the work function it the energy needed to bring an electron from the fermi level to the vacuum level? What are typical values of the binding energy...

Ok, so the question is: A metal has a threshold wavelength for the onset of the photoelectric effect of 662 nm. What is the binding energy (kj/mol) of an electron to the metal surface. I used E=hv to get the photon energy, so is that the binding energy as well? If so, how do i convert it...

Everytime a photon leaves an atom, the energy of that photon is matched by the increase in binding energy of that atom - right? If so would the change of energy in the form of radiation be equivalent to the change of binding energy? Is the aggregate binding energy of particles in the...
