Which of Dalton's postulates about atoms are inconsistent with later observations? Do these inconsistencies mean that Dalton was wrong? Is Dalton's model still useful? Explains

It's the fact that he said atoms are indivisible spheres what pauses limitations on his postulates. Later it was proven that atoms contain subatomic particles: electrons (proved by Thompson), protons (by Goldstein) and neutrons (by Chadwick). However, he was right about the fact that atoms are tiny and spherical!
