An isotope of carbon is shown below. 14C (a) Define the term isotope. (b) State one quantity conserved in a nuclear decay. (c) Calculate the energy released in joules, in the following nuclear reaction. gLi + ²H → He + He The masses of the nuclei are as follows:- Mass of Li is 6.014 u Mass of His 2.102 u Mass of He is 4.002 u Calculate the binding energy and binding energy per nucleon of carbon- 14. Give your answer in MeV. The mass of carbon 14 nucleus is 14.003242 u The rest mass of a proton is 1.007276 u The rest mass of a neutron is 1.008665 u (Use all of these significant figures in your initial calculations) A sample containing cobalt-60 has an initial activity of 4.34 G Bq. Cobalt-60 has a decay constant of 4.167 x 10° s¹¹. Calculate - The half life of Co-60 in years. The number of radioactive atoms in the sample. The mass of radioactive Co-60 in the sample. (d) (e) i. ii. iii. iv. The activity after 10 years.
