- binding energy of a nucleus is positive? 2 answers
When I add up the mass of 6 protons and 6 neutrons in amu, I get a mass that is greater than the mass of carbon. I thought that it should be the other way around, because I have not including binding energy when I add up the mass of the protons and neutrons.
Proton: 1.007276466812 u
Neutron: 1.00866491600 u
Carbon: 12 u
Why is this so?
