If `M_(o)` is the mass of an oxygen isotope `._(8)O^(17), M_(p)` and `M_(N)` are the masses of a proton and neutron respectively, the nuclear binding energy of the isotope is:

Options

A. `(8M_(P)+9M_(N)-M_(O))c^(2)`
B. `M_(O)c^(2)`
C. `(M_(O)-17 M_(N))c^(2)`
D. `(M_(O)-8M_(P))c^(2)`

Answer

A

Explanation

Number of protons=8
Number of neutrons =9
B.E. `=Deltamc^(2) (therefore "Mass in kilogram")`
B.E. `(""_(8)O^(17))=(8M_(P)+_(9)M_(N)-M_( O))c^(2)`
