Question
Chapter 4, Problem 1Q
To determine
The experimental data which is not predicted by Thompson and the reason why he could not make the planetary model of Rutherford- Bohr work.
Expert Solution & Answer
Answer to Problem 1Q
The experimental data which is not predicted by Thompson is light spectrum of hydrogen and he could not make the planetary model of Rutherford- Bohr work because according to his plum-pudding model there is no Coulomb force of attraction between any charges.
Explanation of Solution
In J.J Thompson’s Plum pudding model for the structure of atom, he proposed that electrons (negatively charge particles) are embedded in a uniform positively charged mass, similarly as raisins in a plum pudding and he also said that electric force on electrons is also zero and they do not move rapidly.
Thompson could not make the planetary model of Rutherford- Bohr work because according to his plum-pudding model there is no Coulomb force of attraction between any charges.
Conclusion:
Thus, the experimental data which is not predicted by Thompson is light spectrum of hydrogen and he could not make the planetary model of Rutherford- Bohr work because according to his plum-pudding model there is no Coulomb force of attraction between any charges.

What are the most significant differences between the Bohr model of the hydrogen atom and the Schrödinger analysis? What are the similarities?
In 1927 T. E. Phipps and J. B. Taylor of the University of Illinois reported an important experiment similar to the Stern-Gerlach experiment but using hydrogen atoms instead of silver. This was done because hydrogen is the simplest atom, and the separation of the atomic beam in the inhomogeneous magnetic field would allow a clearer interpretation. The atomic hydrogen beam was produced in a discharge tube having a temperature of 663 K. The highly collimated beam passed along the x direction through an inhomogeneous field (of length 3 cm) having an average gradient of 1240 T/m along the z direction. If the magnetic moment of the hydrogen atom is 1 Bohr magneton, what is the separation of the atomic beam?
