In John Dalton's atomic theory, the following part is not correct:
**d) atoms are indivisible**
While Dalton proposed that atoms were indivisible particles, later discoveries, particularly the discovery of subatomic particles (such as protons, neutrons, and electrons), showed that atoms can indeed be divided into smaller constituents. The other parts of Dalton's theory, such as the ideas that matter is composed of atoms, that atoms combine to form compounds, and that atoms of one element differ from atoms of another, are generally still accepted as valid.
