Nuclei are made up of protons and neutron, but the mass of anucleus is always less than the sum of the individual masses of theprotons and neutrons which constitute it. The difference is ameasure of the nuclear binding energy which holds the nucleustogether. This binding energy can be calculated from the Einsteinrelationship:
Binding energy = delta(mc^2)
The binding energies of nucleons are in the range of millions ofelectron volts compared to tens of eV for atomic electrons.
So take the mass of the parts and convert that to energy
Binding energy = delta(mc^2)
The binding energies of nucleons are in the range of millions ofelectron volts compared to tens of eV for atomic electrons.
So take the mass of the parts and convert that to energy
mass of Cm 248 is 247amu
no of protons is 96 and neutrons is 151
total mass of proton is 96*1.00728+total mass of neutron is 151*1.00866=249.00654amu
difference in mass is 2.00654amu
2.00654*931.494(using 931.494 per amu)
we have =1,869.079971 MeV
per nucleon is 1,869.079971/248≈7.536613 MeV
where 1MeV is =1.6*10^(-13)
plz rate best answer if helpful
