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` is
`= [26 xx 1.00783 u + 30 xx 1.00867 u - 55.9349 u] c^2`.
`= (0.52878 u) (931 MeV u^(-1)` = 492 MeV`.
