Democritus gave a theory, but Aristotle shut him out. Everybody forgot about this, and there was no one looking into this, no progress was being made.

The two earlier scientists whose ideas Dmitri Mendeleev combined were Antoine Lavoisier and John Dalton. Lavoisier established the law of conservation of mass, while Dalton introduced the atomic theory by proposing that all matter is composed of atoms. Mendeleev built upon these concepts to develop the periodic table of elements.
Scientists test ideas about chemical evolution by using computer models.
Democritus proposed that matter is made up of indivisible particles called atoms, which differ in shape and size. Aristotle, on the other hand, believed in four elements (earth, water, air, fire) and did not support the idea of indivisible particles. Later scientists built on Democritus's concept by discovering the structure of the atom, including subatomic particles and the existence of a nucleus.
The scientific revolution led scientists to rely more on empirical evidence, observation, and experimentation to support their ideas, shifting away from traditional reliance on authority and dogma. This emphasis on the scientific method fundamentally changed how scientists validated their ideas and contributed to the development of modern science.

Part of a scientist's job is to publish his ideas, experiments, and theories for other scientists to test and confirm
because atoms are unseen so scientists or philosophers only conclude what comes to their mind, their thoughts and ideas. how will prove this if you can't? that's the disadvantages of always basing yourself on theories of scientists. People believe easily to them because they are philosophers but they didn't know how they conclude their theories.

Scientists usually publish their new ideas in a scientific journal. They can also hold a symposium to discuss the ideas, if they wish.

Scientists no longer believe in Dalton's idea that atoms are indivisible and are the smallest particles of matter because further research has shown that atoms can be broken down into even smaller subatomic particles like protons, neutrons, and electrons. Additionally, Dalton's notion that all atoms of the same element are identical has been revised with the discovery of isotopes, which are atoms of the same element with different numbers of neutrons.
The ancient Greek philosopher Democritus proposed that matter is composed of indivisible particles called atoms, a theory that is similar to the modern atomic theory in physics. His ideas on the existence of atoms and their properties foreshadowed many aspects of today's scientific understanding of matter and its structure.
Marie Curie challenged scientists' ideas about atoms by discovering that radiation emitted by certain elements, such as uranium, could not be explained by existing atomic models. This led to the development of the concept of radioactivity and the realization that atoms could undergo spontaneous changes. Her work paved the way for further research in nuclear physics and the structure of the atom.
atoms cannot be divided

They didn't then and they do not now.
