Which of the following summarizes Rutherford's model of the atom?
a. Electrons are embedded in a positive region of spherical dimension.
b. Electrons revolve around the nucleus without emitting radiation.
c. Electrons revolve around the nucleus like planets move around the sun.
d. Atoms emit radiation only when electrons jump from a higher energy state to a lower energy state.
In Rutherford's model of atom, it was observed that the atom is mostly empty space, the mass of the atom is concentrated at the center (nucleus), and electrons revolve around the nucleus like a mini solar system.
I think it's C.
It is C.
The correct answer is c. Electrons revolve around the nucleus like planets move around the sun.
To find the answer, you can familiarize yourself with the different atomic models proposed throughout history, particularly the Rutherford model. Ernest Rutherford conducted an experiment known as the gold foil experiment, in which he bombarded a thin gold foil with alpha particles. Based on the results of this experiment, Rutherford proposed that atoms have a small, dense nucleus at the center, and the electrons orbit around it in specific energy levels or shells.
Option a is incorrect because Rutherford did not describe the positive region as being spherical. Option b is incorrect because Rutherford's model suggests that electrons do emit radiation as they move in orbits around the nucleus. Option d is incorrect because it relates to the Bohr model, which was developed later and describes the emission of radiation as electrons transition between energy states.
Therefore, based on the understanding of Rutherford's model and the elimination of other options, the correct answer is c. Electrons revolve around the nucleus like planets move around the sun.
