Per NCERT §2.5.2 (significance), what is the key consequence of the uncertainty principle for the concept of an electron's path in an atom?
AElectrons move in elliptical paths only
BElectrons obey classical Newtonian paths exactly
CIt rules out the existence of definite trajectories or paths for electrons in atoms
DElectrons stop moving inside atoms
Answer & Solution
Correct answer: C. It rules out the existence of definite trajectories or paths for electrons in atoms
Per NCERT §2.5.2 significance, no simultaneous knowledge of position + velocity ⇒ no defined trajectory. Electrons described only by probability distributions.
