1. Even though the Bohr model had great success that the theoretical calculated Rydberg constant is so close to the experimental value, still there's small yet detectable discrepancy. What is the factor that is responsible to this discrepancy if taken into account one achieves perfect Rydberg constant?

2. Estimate the size of the aluminum nucleus (Z=13), using a beam of alpha particle having kinetic energy of 7.7 MeV.

Expert Solution

We can determine the rydberg constant by this experimental metgod:

Hydrogen discharge lamp is used to excite the atom to make transitions between energy states producing lights. The light is collimated and sent through diffraction grating. The diffraction grating seperates light into the spectrum. Here good callibration is required which can be done. And from this we can derive hydogen atom visible wavelength. But derived wavelenght have uncertaies which comes due to Heisenbe uncertainty principle.

The Bohr model of the atom was an early attempt, by Danish theoretical physicist Niels Bohr in 1913, to understand the properties of atoms by incorporating the wavelike nature of electrons into an otherwise classical description. The basic assumptions of the model are: a. An electron in an atom moves in circular orbits about a positively charged nucleus, with the Coulomb attraction providing the centripetal force. b. Since electrons are waves, an electron may only (stably) orbit the nucleus at...
