he thought that atoms were the smallest particle and could not be divided any more. the word 'atomos' which atom is derived from, means indivisible. we now know that atoms are made of sub-atomic particles, which are made of quarks (what sort of name is that), and these quarks are made of leptons and gluons.
Democritus's ideas about atoms were limited in that he claimed they were** indivisible and indestructible, lacked experimental evidence, and didn't account for chemical behavior or atomic bonding.** ;
Democritus's atomic theory had limitations, such as the belief that atoms are indivisible, the lack of experimental support, and failure to account for chemical behavior and bonding. His simplistic view of matter also missed the complexity of atomic structures. These shortcomings emphasize the advancements made in atomic theory since his time.
