QUESTION 3 This questiоn is аbоut the element sulfur. (а) Cоmplete the diаgram to show the electronic configuration for a sulfur atom in the ground state. Include labels for each sub-shell. See addendum Figure 3.1 (2) (b) Write an equation for the first ionisation energy of sulfur. Include state symbols. (2) (c) Explain why the first ionisation energy of sulfur is less than the first ionisation energies of both phosphorus and chlorine. (3) (d) A sample of sulfur contains four isotopes. (i) State what is meant by the term isotopes, in terms of subatomic particles. (2) (ii) Calculate the relative atomic mass of sulfur in this sample. Give your answer to two decimal places. (2) 3.4 The weight of the metal block is 0.68 N. Show that the moment of the weight of the metal block about point P is approximately 2.9 N cm. (e) The mass spectrum of a sample of sulfur with 32S as the only isotope is shown. (i) Calculate the number of sulfur atoms in the molecular ion. You must show your working. (1) (ii) Suggest the formula of the most stable ion shown by this spectrum. (2) TOTAL QUESTION 3: [14]
