(a)
Interpretation:
The electronic transition corresponds to line B and C has to be identified.
(a)

Explanation of Solution
The given lines are corresponding to
(b)
Interpretation:
From the wavelength of line c, the wavelength of line A and B has to be calculated.
Concept Introduction:
Bohr developed a rule for quantization of energy that could be applicable to the electron of an atom in motion. By using this, he derived a formula for energy levels of electron in H-atom.
(b)

Answer to Problem 7.119SP

(c)

Answer to Problem 7.119SP
The energy required to eject an electron from
Explanation of Solution
The initial state is
(d)
Interpretation:
The physical significance of continuum has to be explained.
(d)

Explanation of Solution
The energy levels are closely packed when the n values become larger and it leads to continuum of lines. Electrons have been removed from atom when the continuum starts. Therefore, there will be no quantized energy levels associated with electron.

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur).
