Find the binding energy of .26^56 Fe. At...

Find the binding energy of `._26^56 Fe`. Atomic mass of `.^56 Fe` is `55.9349 u` and that of `.^1 H` is `1.00783 u`. Mass of neutron `= 1.00867 u`.

Text Solution

Verified by Experts

The number of protons in `(._(26)^(56)Fe)=26` and the number of neutrons `=56-26=30`. The binding energy of `(._(26)^(56)Fe) =26` and the number of neutrons `=56-26 =30`. The binding energy `(._(26)^(56)Fe)`
`=[26 xx 1.0078 u+30 xx 1.00867 u-55.9349 u]c^(2)`
`=(0.52878 u)c^(2)`
`=(0.52878 u)(931 MeV//u) =492 MeV.`
