\[\Delta m=m_n-m\]
Variables
dm[Δm]mass defect (kg)
mnsum of individual nucleon masses (kg)
mmeasured nucleus mass (kg)
Description
What is this formula?
This formula calculates the mass defect of an atomic nucleus. The mass defect is the difference between the sum of the masses of all separate nucleons and the actual measured mass of the nucleus.
When to use it
Use this formula in nuclear physics when calculating nuclear binding energy, analyzing isotope stability, and studying nuclear reactions.
Example
Given:
mn=6.695×10^-27 kg
m=6.691×10^-27 kg
Formula:
Δm=mn−m
Substitution:
Δm=(6.695×10^-27)-(6.691×10^-27)
Result:
Δm=4×10^-30 kg
