1) Neutral hydrogen can be modeled as a positive point charge +1.6×10−19C surrounded by a distribution of negative charge with volume density given by ρE(r)=−Ae−2r/a0 where a0=0.53×10−10m is called the Bohr radius, A is a constant such that the total amount of negative charge is −1.6×10−19C, and e = 2.718... is the base of the natural log. [Hint: Do not confuse the exponential number e with the elementary charge e which uses the same symbol but has a completely different...
4. Estimate the transition frequency for the poryphyrin molecule from m-11 to m 12, assuming that the pi electrons can be modeled as a particle in a ring of radius 440 picometers. (C 7. The most probable distance of the electron from the nucleus in a 1ls state hydrogen atom (with wavefunction V1) can be determined by 21. A (A) solving the eigenvalue equation: Rvw rV., finding the maximum in the 1s radial distribution function by differentiation. (C) substituting vi,...
