What does Dalton’s atomic theory suggest about atoms in chemical reactions?

Dalton’s atomic theory fundamentally suggests that during chemical reactions, atoms do not change themselves; rather, they are simply rearranged to form new compounds. This idea emphasizes that the distinct identities of atoms are maintained throughout the reaction process. Instead of being created or destroyed, which would contradict the law of conservation of mass, atoms maintain their individual properties while forming different molecules. Each type of atom retains the same number of protons and electrons, ensuring that their intrinsic characteristics are preserved. This understanding laid the groundwork for modern chemistry, providing a clear framework for how substances interact at the atomic level.
