Rutherford aimed to investigate the arrangement of electrons within an atom by studying the behavior of alpha particles as they interacted with a thin gold foil.
Thomson’s model proposed that atoms consisted of a positively charged sphere with embedded electrons, suggesting that atoms were not indivisible but composed of smaller particles.
In Thomson’s model, electrons were illustrated as small particles distributed within the positively charged sphere, similar to seeds in a watermelon.
