Questions and Answers

What is the central contrast in Rutherford's quote regarding the atom?

The distinction between the atom's theoretical representation and its observable behavior.

The shift from viewing the atom as a simple, solid entity to a more complex, non-material structure. (correct)

The difference between the atom's perceived hardness and its actual color.

The evolution of atomic models from colored spheres to colorless spheres.

The phrase 'in order to explain the facts' in Rutherford's quote most directly implies that:

his personal preferences ('taste') influenced his atomic model.

atoms are inherently impossible to fully comprehend.

experimental evidence and scientific findings necessitated a revised understanding of the atom. (correct)

his initial atomic model was sufficient for all observations at the time.

When Rutherford describes his early view of the atom as a 'nice hard fellow, red or gray in color, according to taste,' what primary aspect of atomic models is he downplaying?

The role of color in atomic interactions.

The variability of atomic size and shape.

The importance of experimental verification in scientific models.

The complexity and non-material nature of the atom. (correct)

Given the context of Rutherford's quote being from a 1934 after-dinner address at the Cavendish Laboratory, it is most likely that his reflection on the atom's nature is:
