Question

Explain binding energy curve.Write its importance .What is gamma decay? Explain with example.

Answer 1

$Bindingenergycurve:-$ The fact that there is a peak in the binding energy curve in he region of stability near iron means that either the breakup of heavier nuclei $($fission$)$ or the combining of lighter nuclei $($fusion$)$ will yield nuclei which are more tightly bound $($ less mass per nucleon$).$

Importance of Binding energy curve$:-$ Nuclear binding energy is defined as the energy required to break up a nucleus into its individual nucleons $i.e.,$ protons and neutrons$.$ The more important than the total binding energy is the energy per nucleon against mass number$.$

$gammadecay:-$ One of the three main types of radioactive decay is known as gamma decay $\left(\gamma -decay\right).$

During gamma decay$,$ the energy of the parent atom is changed by the emission of a photon$.$ The resulting energy of the daughter atom is lower than the parent atom$.$ A photon is a massless particle with a very small wavelength$.$
