The carbon isotope ¹²₆C has a nuclear mass of 12·000000 u. Calculate the binding energy of its nucleus. Given mp = 1·007825 u; mn = 1·008665 u.
Differentiate between nuclear fission and fusion.
Assertion (A) : Nuclear fission reactions are responsible for energy generation in the Sun. Reason (R) : Light nuclei fuse together in the nuclear fission reactions.
Draw a diagram to show the variation of binding energy per nucleon with mass number for different nuclei and mention its two features. Why do lighter nuclei usually undergo nuclear fusion ?
What is meant by ionisation energy? Write its value for hydrogen atom.
Define the term, mass defect. How is it related to stability of the nucleus?
