The Rutherford-Bohr model is a planetary model in which the electron is assumed to revolve around the nucleus in circular orbits. Just as strings on a guitar have different frequencies and octaves, atoms with different protons and electrons have different wave patterns The electron can only have certain energies, and this explains a tremendous amount of things. were filled with nonbonded C atoms at the optimal distance apart, Assume the optimal van der Waals distance is 4A, (nucleus to nucleus) for C atoms interacting with other C atoms, and assume the prokaryotic cell is, a rod-shaped bacterium with a length of 2. 119) What is the main difference between a conceptual model and a physical model?
