Democritus believed that different types of atoms could combine in different arrangements to form what?

Democritus proposed that atoms are the fundamental building blocks of matter and that they can combine in various arrangements. This concept leads to the formation of different substances, as the unique combinations and arrangements of atoms give rise to distinct characteristics and properties of those substances.

In his atomic theory, Democritus emphasized that the shape, size, and arrangement of atoms would determine the nature of the material they compose. By combining atoms in different ways, countless varieties of matter can be created, which aligns with the idea of forming different substances. This represents a foundational principle in understanding the composition of matter and laid groundwork for future developments in chemistry and physics.
