Dmitri Mendeleev came up with the system for arranging the elements so he is also given credit for the modern Periodic Table. He arranged them based on each elements increasing atomic weight.
What philosopher's ideas are being described?He believed in the theory of "ideas" and "forms."Elements in the physical world-a desk, a man, a dog-are imperfections of shadows of the eternal, perfect ideas of a desk, a man, a dog.Plato

ideas
The scientist credited with reviving Democritus's ideas about matter and atoms is John Dalton. In the early 19th century, Dalton proposed the atomic theory, which reintroduced the concept of atoms as fundamental building blocks of matter. His work laid the foundation for modern chemistry by establishing that each element consists of unique atoms and that these atoms combine in specific ratios to form compounds.
The five main points of John Dalton's atomic theory are as followed: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element. · Atoms of one element can combine with atoms of other elements to form compounds. · A given compound always has the same relative numbers of types of atoms. · Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.
Part of a scientist's job is to publish his ideas, experiments, and theories for other scientists to test and confirm
Dalton's four ideas about matter, known as Dalton's atomic theory, are: 1) All matter is composed of indivisible atoms, which cannot be created or destroyed. 2) Atoms of the same element are identical in mass and properties, while atoms of different elements are different. 3) Atoms combine in simple whole-number ratios to form compounds. 4) In a chemical reaction, atoms are rearranged but remain unchanged.

Before Mendeleev, Dobereiner, De-chancourtis, Newland and Lother Meyers had already given their respective periodic arrangement of elements, but none of the models were accepted as they had many limitations...
