Chapter 7.6, Problem 4Q
Interpretation Introduction

Interpretation:

When iron in the porphyrin ring is reduced from  Fe3+ to Fe2+, the changes in the porphyrin structure has to be accounted.

Concept Introduction:

Atomic radii: As the electron is added to the ion or neutral atom, size increases because electron–electron repulsion occurs and also effective nuclear charge decrease because due to addition of one more electron.

Phosphorus (P) is present in a germanium (Ge) sample. Assume that one of its five valence electrons revolves in a Bohr orbit around each P+ ion in the Ge lattice. (a) If the effective mass of the electron is 0.17 me and the dielectric constant of Ge is 16, find the radius of the first Bohr orbit of the electron. (b) Ge has a band gap (Eg) of 0.65 eV. How does the ionization energy of the above electron comparing to Eg and kBT at room temperature?
Look at the picture and fill in the gap, please.
consider the following equation
