Definite and Multiple Proportions The theories of definite and multiple proportions offered critical evidence for Dalton’s atomic hypothesis. This led to the plum pudding model and eventually to Ernest Rutherford’s nuclear model, which identified a dense nucleus surrounded by electrons.

This solidified the idea that weight changes in experiments were due to the loss or capture of gases, not the annihilation of substance, aligning theoretical mechanics with laboratory results. He incorrectly assumed that all atoms of an element were absolutely identical, ignoring the existence of isotopes—atoms of the same element with different masses.
For instance, water is always composed of hydrogen and oxygen in a mass ratio of roughly 1:8. Crucially, atoms cannot be created, destroyed, or subdivided in chemical processes; they simply rearrange themselves.

Furthermore, his theory struggled to explain phenomena like allotropy, where the same element exhibits different properties, or the nature of chemical bonding beyond simple juxtaposition. Thomson in 1897 shattered the notion of the indivisible atom, revealing a complex internal structure.
