NEET Chemistry: Chemistry Class 11: Structure of Atom questions with solutions

Q1. The current model of atomic structure is the:

1. Quantum mechanical model
2. Quantum physiochemical model
3. Atomic mass theory
4. None of the above

Answer: Quantum mechanical model

The accepted modern description of atomic structure is the quantum mechanical model because it treats electrons as probability distributions rather than particles in exact circular orbits. This matches experimental evidence better than older atomic models.
