• Binding Energy: The amount of energy released when a nucleus is formed from its components.• Mass defect ΔM = Z*Mp + N*Mn-MAZ= Atomic no., N= No. of neutrons Mp = Mass of proton, Mn = Mass of neutron,MA= Atomic Mass
Binding Energy = ΔMc2 = ΔM * 931.5 MeV
Binding Energy Per Nucleon = ΔMc2 = (ΔM * 931.5 MeV)/ (no. of protons + no. of neutrons)
Here ΔM can be calculated from above equation as:
Z=26, N=30, Mp=1.0078 u, MN= 1.0086 u. ΔM = 26(1.0078) +30(1.0086)-55.9349ΔM = 0.5259 u
Binding energy = Mass defect × c²Mass defect = mass of the element - observed massMass defect = (25×1.00728 + 30×1.00867) - 54.938047 = 0.504053 amuConverting the mass from kg...
Solution:The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance.Average atomic mass = f1M1 + f2M2 +… + fnMn where...
There are 6 protons, neutrons and electrons in the carbon-12 atom. Thus, the mass percentage of neutrons equals:6*1.0087/(6*1.0087+6*1.0073+6*5.4858*10^-4)=0.50021110822=50,021110822%.Solution: 50,02%.
