Thomson’s Model (1897) - “Plum Pudding Model”

Thomson proposed that atoms were made of a positively charged "pudding" with negatively charged electrons embedded inside, like raisins in a pudding.

Dalton’s Model (1803) - “Billiard Ball Model”

Dalton believed atoms were tiny, indivisible spheres that combined to form compounds in fixed ratios.

Picture: Inside the model, there were atoms combined in fixed ratios (for example, two circles together for H₂, three circles together for H₂O).
