Oxygen comes in heavy and light varieties, or isotopes, which are useful for paleoclimate research. Like all elements, oxygen is made up of a nucleus of protons and neutrons, surrounded by a cloud of electrons. All oxygen atoms have 8 protons, but the nucleus might contain ...

WebFind the mass defect of oxygen-16 if the measured atomic mass is 15 amu. 1 proton = 1 amu, 1 neutron = 1 amu, and 1 electron = 0 amu. Calculate the nuclear binding energy of oxygen-16 given that 1 amu = 1 ́ 10 -27 kg. PART B – NUCLEAR DECAY. Write equations for the following nuclear decay reactions. Make sure that both mass numbers and ... WebTo find the binding energy, add the masses of the individual protons, neutrons, and electrons, subtract the mass of the atom, and convert that mass difference to energy. For carbon-12 this gives: Mass defect = D m = 6 * 1.008664 u + 6 * 1.007276 u + 6 * 0.00054858 u - 12.000 u = 0.098931 u
