Answer :

Final answer:

Gases played a significant role in the development of atomic theory, with key contributions from scientists like John Dalton and Amadeo Avogadro.


Explanation:

Gases led most directly to the development of atomic theory. The behavior of gases at the macroscopic level led scientists to investigate the microscopic properties of matter, ultimately contributing to the foundation of atomic theory.

Chemists like John Dalton and Amadeo Avogadro made significant contributions to the atomic theory, allowing for a more systematic approach to understanding chemistry and quantifying the number of particles in gases.

Discoveries in the 19th century, such as the periodic table and the development of electrochemistry, further solidified the concept of atoms as the basis of matter.
