Oxygen-15, vanadium-51, and bismuth-209 have atomic masses of 15.003065 amu, 50.943964 amu, and 208.980399 amu, respectively. What is the nuclear mass of each isotope? (mass of electrons = 5.485799×10–4 amu)
Which of the following best describes the concept of mass defect?
How many atomic mass units (amu) is a helium atom with 2 protons, 2 neutrons, and 2 electrons, given the mass of a proton and neutron is approximately 1 amu each?
