What was the main problem with Democritus idea of the atom?
2,500 years ago, Democritus suggested that
all matter in the universe was made up of tiny, indivisible, solid objects he called “atomos
.” However, other Greek philosophers disliked Democritus’ “atomos” theory because they felt it was illogical.
What did John Dalton find out about atoms?
A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1)
Elements consist of indivisible small particles (atoms)
. (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed.
What was John Dalton’s experiment?
Dalton’s experiments on gases led to his discovery that
the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space
. In 1803 this scientific principle officially came to be known as Dalton’s Law of Partial Pressures.
What did Democritus say about matter?
The theory of Democritus held that
everything is composed of “atoms,” which are physically, but not geometrically, indivisible
; that between atoms, there lies empty space; that atoms are indestructible, and have always been and always will be in motion; that there is an infinite number of atoms and of kinds of atoms, …

whereas Dalton atomic theory is a comparatively modern, scientific theory that we cannot discard due its important statements.

What are Democritus four principles of the atom?
Democritus believed that
atoms were uniform, solid, hard, incompressible, and indestructible
and that they moved in infinite numbers through empty space until stopped. Differences in atomic shape and size determined the various properties of matter.
What did Democritus teach?

there were substances called atoms and that these atoms made up all material things
. The atoms were unchangeable, indestructible, and always existed.
