Firstly, An ionic bond results when the sharing is so unequal that fully charged ions form. Electronegativity difference can be used to predict bond type. Secondly, one method to classify bonds based on this difference can be described as follows. If the electronegativities differ by less than 0.4 units, the bond can be classified as nonpolar covalent. If the difference is between 0.4 and 2.0 units, the bond is classified as polar covalent, and if the difference is more than 2.0 units, the bond is substantially ionic.
Answer:
See explanation
Explanation:
Number of protons = 28
Number of neutrons = 28
Mass of each proton = 1.007277 amu
Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu
Mass of each neutron = 1.008665 amu
Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu
mass defect of nickel-56 = 0.4667 amu
Binding energy = Δmc^2
Binding energy = 0.4667 *(3 * 10^8)^2
Binding energy =4.2 * 10^16 J
Binding energy per nucleon = 4.2 * 10^16 J/56
Binding energy per nucleon = 7.5 * 10^14 J
