Zorluk: KolayMass Defect and Binding Energy

The mass defect of a nitrogen nucleus 714N^{14}_{7}\text{N} is calculated to be 0.112 u0.112\text{ u}. Taking 1 u=931.5 MeV1\text{ u} = 931.5\text{ MeV}, what is the total binding energy of the nucleus in MeV\text{MeV}?

Cevap: 104.328 MeV

Cevap

The total binding energy of the 714N^{14}_{7}\text{N} nucleus is 104.328 MeV104.328\text{ MeV}.
The total binding energy of a nucleus is equal to the mass defect multiplied by the energy equivalent of one atomic mass unit (931.5 MeV/u931.5\text{ MeV/u}). Calculating 0.112 u×931.5 MeV/u0.112\text{ u} \times 931.5\text{ MeV/u} gives 104.328 MeV104.328\text{ MeV}.

Adım Adım Çözüm

1
Apply the binding energy formula Eb=Δm×931.5 MeV/uE_b = \Delta m \times 931.5\text{ MeV/u}.
Eb=0.112 u×931.5 MeV/u=104.328 MeVE_b = 0.112\text{ u} \times 931.5\text{ MeV/u} = 104.328\text{ MeV}.
The binding energy is obtained by converting the mass defect directly into its energy equivalent.
