Which of the following conclusions could not be derived from Rutherford's 
-particle scattering experiment?
A
Most of the space in the atom is empty.
B
The radius of the atom is about 
while that of nucleus is 
.
while that of nucleus is . C
Electrons move in a circular path of fixed energy called orbits.
D
Electrons and the nucleus are held together by electrostatic forces of attraction
Text Solution
Verified by ExpertsThe correct answer is:
C
Concept of electrons move in a circular path of fixed energy called orbits was put forward by
Bohr and not derived from Rutherford's scattering experiment. Out of a large number of circular orbits theoretically possible around the nucleus, the electron revolve only in those orbits which have a fix value of energy. Hence, these orbits are called energy level or stationary states.
