Interpretation: To determine the binding energy of the
Concept introduction:Mass defect:
The nucleus of each atom (aside from
Mass and energy are related by following equation.
E = Energy
M = mass
C =
Calculated mass of nucleus:
The calculated mass of nucleus is equal to the sum of masses of its protons and neutrons.
mH = mass of proton
mn= mass of neutron.
Loss of mass and liberation of energy are related by Einstein’s equations.
Binding energy:
The binding energy is the energy that would be needed to disassemble a nucleus into individual nucleons.
The formula of binding energy
Loss of mass and liberation of energy are related by Einstein’s equations.
Answer to Problem 14.41PAE
Solution: The binding energy of
Explanation of Solution
Given information: Experimentally determined mass of
Formula used:
where,
E= binding energy
c= speed of light
Calculation: The given
The calculated mass is equal to the sum of masses o three protons and seven neutrons.
Let’s write formula:
Therefore, calculated mass of
Let’s calculate the mass defect:
Therefore, mass defect of
Let’s calculate the binding energy:
Therefore,
Let’s calculate the released energy when one mole of
The released energy when one mole of
Therefore, the binding energy of

- Plutonium was detected in trace amounts in natural uranium deposits by Glenn Seaborg and his associates in 1941. They proposed that the source of this 239Pu was the capture of neutrons by 238U nuclei. Why is this plutonium not likely to have been trapped at the time the solar system formed 4.7109 years ago?arrow_forwardThe following nuclei do not lie in the band of stability.
