What are the 4 parts of the atomic theory

Atomic theory, a cornerstone of modern science, comprises four key parts: all matter is made of atoms, atoms of the same element are identical, atoms combine in whole-number ratios to form compounds, and chemical reactions rearrange atoms, not create or destroy them.
