Per NCERT, what was the MAJOR DRAWBACK of the Rutherford nuclear model?
AIt did not allow positive nucleus
BIt conflicted with the law of conservation of mass
CIt denied existence of electrons
DIt could not explain the stability of the atom — a classically accelerating electron should radiate and spiral into the nucleus in ~10⁻⁸ s
Answer & Solution
Correct answer: D. It could not explain the stability of the atom — a classically accelerating electron should radiate and spiral into the nucleus in ~10⁻⁸ s
Per NCERT §2.2.5, classical electromagnetic theory says an orbiting (accelerating) electron must radiate, collapsing the atom in ~10⁻⁸ s. Rutherford could not resolve this.
