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. `(M_(o)-8M_(p))C^(2)`
B. `(M_(o)-8M_(p)-9M_(N))C^(2)`
C. `M_(o)C^(2)`
D. `(M_(o)-17M_(N))C^(2)`

Answer

B

Explanation

Nuclear binding energy `=`[mass of nucleus`-`mass of nucleons] `C^(2)=(M_(o)-8M_(p)-9M_(N))C^(2)`
