🚨 We will cover Chemistry Chapter (Unit) 3 Atomic Structure FBISE (Federal Board) 9th. Specifically, we will discuss atomic models, Dalton's Atomic Model, Rutherford's Experiment / Atomic model, Bohr’s Atomic Theory / Model, Quantum Mechanical Model, Heisenberg Uncertainty Principle and lastly de Broglie hypothesis. In this video, you will learn:

💠 Atomic Model (a conceptual tool to represent atom structure and behavior, evolving with experimental evidence)
💠 Dalton’s Model (1803) (atoms are indivisible, identical for each element, combine in simple ratios, and cannot be created or destroyed)
💠 Rutherford’s Model (1911) (atoms have a tiny, dense, positively charged nucleus with electrons orbiting around empty space; based on α-particle scattering experiments)
💠 Bohr’s Model (1913) (electrons revolve in fixed energy levels (orbits), absorb/emit light when jumping between levels, explaining hydrogen’s line spectrum)
💠 Quantum Mechanical Model (treats electrons as wave-particle entities in probability regions called orbitals; replaces fixed orbits with electron clouds)
💠 Heisenberg Uncertainty Principle (it’s impossible to know an electron’s exact position and momentum simultaneously)
💠 de Broglie Hypothesis (1924) (electrons exhibit dual wave-particle nature, foundational for quantum mechanics)
