According to Rutherford atomic model, the electrons revolve around the nucleus in ________ paths.
-
A.
Elliptical
-
B.
Circular
-
C.
Linear
-
D.
Radial
Correct Answer:
B. Circular
Explanation:
According to Rutherford's atomic model, proposed in 1911 following his gold foil experiment, an atom consists of a tiny, dense, and positively charged center called the nucleus. Rutherford suggested that negatively charged electrons do not remain stationary but revolve around this central nucleus at very high speeds. He specifically described these paths as circular orbits, drawing a comparison to the way planets revolve around the Sun in a solar system. While later models by Bohr and quantum mechanics refined these paths, the original Rutherford model explicitly defined the motion of electrons as occurring in circular paths. Therefore, circular is the correct choice.
