Atomic Models — Mains Questions

Trace the evolution of atomic models from Dalton to the Quantum Mechanical Model, highlighting the experimental evidence that led to the rejection of each preceding model. Discuss the significance of this evolutionary process in scientific inquiry.

Compare and contrast Bohr's Atomic Model with the Quantum Mechanical Model, focusing on their fundamental postulates, explanatory power, and limitations. How has the Quantum Mechanical Model influenced our understanding of chemical bonding and the periodic table?

The evolution of atomic models is a testament to the iterative nature of scientific discovery. Discuss this statement with reference to the contributions of J.J. Thomson and Ernest Rutherford, highlighting how their experiments challenged existing paradigms and paved the way for a more accurate understanding of the atom.
