If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact Atomic Mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
A mass defect is the difference in mass between a atom and the sum of mass between an atom and the number of the protons, neutrons, and electrons of the atom.
The binding energy is the mass defect, times the square of the speed of light.The amount stated seems to be an awfully high mass defect, though.
The mass of a nucleus is subtracted from the sum of the masses of its individual components.
If you really meant to ask "What is the mass defect of oxygen-16," this is how you do it. mass defect = # of protons x mass of one proton + # of neutrons x mass of one neutron - mass of the nucleus The atomic number of oxygen-16 is 8, so there are 8 protons. The mass of one proton is approximately 1.0073 amu. The Atomic Mass of oxygen-16 is 16, so there are 8 neutrons in oxygen-16. (Atomic mass of 16 minus atomic number of 8 = # of neutrons in oxygen-16.) The mass of one neutron is approximately 1.0087 amu. The mass of the nucleus of oxygen is 16. Now substitute the values into the "mass defect" equation: mass defect = 8x1.0073+8x1.0087-16=approximately 0.128 amu.
mass defect
Well... one could be the same mass as 12 protons + 12 neutrons + the mass defect.
Nuclear binding energy is the energy required to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of the masses of its individual protons and neutrons. The mass defect is converted into nuclear binding energy according to Einstein's famous equation, E=mc^2, where E is the energy, m is the mass defect, and c is the speed of light.

E = MC2; energy is equal to a quantity of matter. When protons (and neutrons) combine in an atomic nucleus, the resultant mass is less than that of the individual particles. This is the mass defect, and the 'missing' mass is a result of the energy binding the particles together. The larger the mass defect for a particular atom (isotope), the larger the amount of nuclear binding energy.
The binding energy is the mass defect, times the square of the speed of light.The amount stated seems to be an awfully high mass defect, though.

The mass defect represents the mass converted to binding energy
The mass of a nucleus is subtracted from the sum of the masses of its individual components.
It allows you to calculate the corresponding energy.
