Energy Req'd to Remove Nucleon from 12_6 C Atom

[desmond iking]

Homework Statement

lets's say the binding energy of 12_6 C atom is 2.00MeV .. what's the energy required to remove a nucleon form the 12_6 C atom

Homework Equations

The Attempt at a Solution

is it 2.00MeV or 2.00MeV / 12 ?

binding energy is defined as the energy required to separate all the nucleon in the atom...[/B]

Suppose we remove one nucleon at a time. Is the energy required the same at each step?

 

[desmond iking]

Same?

 

[haruspex]

Same?

I think not. Look at http://upload.wikimedia.org/wikiped...inding_energy_curve_-_common_isotopes.svg.png. It shows e.g. that removing one nucleon from C12 will reduce the binding energy by a bit more than one twelfth.
I don't think there's a simple answer to your question. Is it homework/coursework?

this is homework

If you remove a proton, what type of nucleus is left? Can you find the binding energy of this nucleus? Can you then use this information to find the energy required to remove the proton?

What if you remove a neutron instead of a proton?

If you remove a proton, what type of nucleus is left? Can you find the binding energy of this nucleus?

That'll certainly work, but the casual wording of the question suggests the author thinks there is some generic route to an answer. Desmond, is this the exact wording, or have you reworded it to make it sound more generic?
