1) All matter is made of atoms.
2) Atoms of a given element are identical in size, mass and chemical
3) Atoms of different elements have different masses and properties.
4) Compounds are formed by a combination of two or more different kinds of atoms. The elements subdivided, created, or destroyed, but merely rearranged in their compounds with other elements. They can be combined, separated, or changed in the way in which they are arranged.
Atoms are made up of the smallest form of matter
Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.
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.
John Dalton further developed Democritus's ideas by proposing the modern atomic theory, which stated that each chemical element is composed of its own unique kind of atom. Dalton's theory also included the concept that atoms are indivisible, and that chemical reactions involve the rearrangement of atoms.

Democritus' method of explaining nature through philosophy and reasoning rather than systematic experimentation and quantitative analysis hindered the acceptance of Dalton's ideas because it lacked empirical evidence and precise measurements. Dalton's atomic theory required experimental support and quantifiable data, which was contrary to the more abstract and qualitative approach of Democritus.
