🌟 Quantum Mechanical Model of Atom – Notes (NEET Level)  Quantum Mechanical Model of Atom showing electron cloud and wave function ψ explained visually for NEET students. 1. Limitation of Classical Mechanics Classical mechanics is based on Newton’s laws of motion . It explains motion of big (macroscopic) objects like: falling stone planets These objects behave like particles only . 2. Failure of Classical Mechanics Classical mechanics fails for microscopic particles like: electrons atoms molecules Reason: It does not consider wave nature of matter It ignores Heisenberg’s uncertainty principle 3. Wave-Particle Duality Small particles (electrons etc.) show dual nature : Particle nature (like tiny balls) Wave nature (like waves) This is called wave-particle duality of matter 4. Quantum Mechanics Definition Quantum mechanics is a branch of science that: studies motion of microscopic particles considers both wave and particle nature It gi...
