Which landmark experiment decisively rejected the "Plum-Pudding" atomic model and introduced the con — Atomic Structure Chemistry Question

💡 Solution & Explanation

Rutherford's $\alpha$ -scattering experiment showed that most of an atom's mass and its positive charge are concentrated in a tiny central nucleus, disproving Thomson's plum-pudding model where mass and charge were thought to be uniformly distributed. [48-50, 62]
