Why did Dalton use the billiard ball as a model?
Dalton used the billiard ball as a model to represent atoms because it illustrated the concept of indivisible particles that could combine in fixed ratios to form compounds. The smooth, hard surface of billiard balls symbolized the uniformity and solidity of atoms, allowing for a clear visualization of how they interacted in chemical reactions. This simple and tangible analogy helped convey the foundational ideas of atomic theory to a broader audience.
