4. (a) The four lowest electronic energy levels of a titanium atom are characterized below: Term 25+¹LJ Degeneracy Energy / cm³¹ 2J+1 3F2 5 0 3F3 7 170 3F4 387 5F₁ 6557 Other electronic energy levels are much higher than that of 5F₁. Consider a gaseous sample of titanium at the boiling point of Ti, 3287 °C. (i) Calculate the electronic partition function of a titanium atom by direct summation. (ii) Consider a mole of these atoms and determine the fraction of atoms at each energy level. (iii) Calculate the electronic contribution to the molar internal energy of gaseous Ti atoms. (iv) Calculate the electronic contribution to the molar entropy of gaseous Ti atoms. (v) What is the temperature when the populations of the second and third energy level (³F3 and ³F4) are equal?
