democritus proposed that matter was composed of indivisible particles called atoms over two thousand years ago. by 1803, dalton created a model that proposed that atoms were solid, indivisible spheres, and that atoms of a given element were identical. werner heisenberg and erwin schrödinger developed the quantum mechanical model in 1926. provide at least one reason that our understanding of atoms has changed over time.

Explanation:

Advances in technology have allowed for more precise observations and experiments. For example, new - generation microscopes and particle accelerators have revealed sub - atomic structures that were previously unknown, leading to a change in our understanding of atoms.

Answer:

Advances in technology enabling more precise observations and experiments.
