Question

A Review | Constants Periodic Table Part B Learning Goal: To learn how to calculate the binding energy of a nucleus. The actual measured mass of a fluorine-19 atom is 18.998403 amu . What is the mass defect, Am, for a fluorine-19 nucleus? Express your answer in atomic mass units using six significant figures. The measured masses of nuclei are consistently lower than predicted by the sum of their particles. This discrepancy is called the mass defect, and it can be used to calculate the nuclear binding energy according to Einstein's famous equation ► View Available Hint(s) AE = Amca VO AO O 2 ? where AE is the energy produced, Am is the mass lost, and c= 3.00 x 108 m/s. Nuclear binding energy is the energy holding the nucleons together and is a measure of nuclear stability. Am = amu Submit

Answer 1

- in Atomic number of Fluorine, = 9 Mass number of sluorine - 19. - No. of profons = 9 No- of neutrons a 1992 to Marr defect am = bx mp + loxmn - 18.99 Now, mp = 1.00727647 amu (hom internet) mna 1.0086654 anu (born interned) . Am = 9x1.00727647 + 10x1-0086654 - 18.998403 amu & Am = 0.15 373923 amu 0.153739 amu 2) Totat binding energy - Am x c2 - Binding energy per nuclean = Amxe2 lotg = 0.15373923 x 1.66053904x 10" /nudem, 19 Lolo 1.2092 6839 1.6x10-13 - Mereuden = 7.55 79 27436 Mex/ruchen 2 7055 79 3 Mev/nuchen
