Atomic Models and Subatomic Particles

The video tutorial explores the evolution of atomic models, starting with Dalton's billiard ball model, followed by Thomson's plum pudding model, Rutherford's nuclear model, and Bohr's planetary model. It discusses the characteristics and limitations of each model, highlighting the discovery of subatomic particles like electrons, protons, and neutrons. The tutorial also emphasizes the importance of energy levels in Bohr's model and concludes with a call to action for viewers to engage with the channel and access additional resources.
