Calculating Binding Energy of Deuterium Nucleus

In summary, the average binding energy per nucleon in the deuterium nucleus is 1.114 MeV/Nucleon and the ratio of the binding energy per nucleon to the binding energy per electron in deuterium is approximately 1:83134, indicating that the neutron is held more tightly than the electron.

Homework Statement



{a} Calculate the average binding enrgy per nucleon in the deutrium nucleus
{b} 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 deutrium. Which particle is held more tightly, the electron or the neutron?

Homework Equations



E=mC^2

The Attempt at a Solution



a)

m(deuterium)=2.014102u
Has 2 nucleon
m(electron)=0.000549u
m(proton)=1.007276u
m(neuron)=1.008665u

m(Nucleus)=(2.014102u)-(0.000549u)=2.013553u
m(Nucleons)=(1.007276u)+(1.008665u)=2.015941u
[Delta]m=(2.015941u)-(2.013553u)=2.388x10^-3u
-Converting to Kg-
2.388x10^-3u = 3.965x10^-30kg

E(binding)=(3.965x10^-30kg)(3.0x10^8)^2=3.5685x10&-18J=2227282.752eV=2.227MeV
Eav(binding)=[2.227MeV]/[2 nucleons] =1.114MeV/Nucleon

The average binding energy per nucleon in the deuterium nucleus is 1.114 MeV/Nucleon

b)

E(Electron binding)=13.4eV/1 electron E(Nucleon binding)=1.114Mev/1 nucleon

[E(Electron binding)]/[E(Nucleon binding)] = [1.114MeV]/[13.4x10^-6MeV] =83134.33

The ratio of the binding energy per nucleon to the binding energy per electron in deuterium is 1:83134. More energy is required to remove the neutron than the electron.

I'm thinking my answer is correct, could someone kindly verify?

Thank you!

I can confirm that your calculations and reasoning are correct. The average binding energy per nucleon in the deuterium nucleus is indeed 1.114 MeV/Nucleon and the ratio of the binding energy per nucleon to the binding energy per electron in deuterium is approximately 1:83134. This means that the neutron is held more tightly than the electron in the deuterium nucleus. Great job on your calculations!
 

1. What is the formula for calculating the binding energy of a deuterium nucleus?

The formula for calculating the binding energy of a deuterium nucleus is E = mc² - (mp + mn), where E is the binding energy, m is the mass, c is the speed of light, and subscript p and n refer to the proton and neutron, respectively.

2. How is the mass of a deuterium nucleus determined?

The mass of a deuterium nucleus can be determined experimentally using mass spectrometry or by calculating the mass from the sum of the masses of its constituent particles (protons and neutrons).

3. What is the unit of measurement for binding energy?

Binding energy is typically measured in units of electron volts (eV) or mega electron volts (MeV). These units represent the amount of energy required to remove an electron from an atom or nucleus, respectively.

4. How is the binding energy of a deuterium nucleus related to nuclear stability?

The higher the binding energy of a nucleus, the more stable it is. This is because a higher binding energy means that the nucleus is more tightly bound and requires more energy to break apart.

5. Can the binding energy of a deuterium nucleus be changed?

The binding energy of a deuterium nucleus is a constant value based on the masses of its constituent particles. It cannot be changed without altering the number of protons and/or neutrons in the nucleus.
