He discovered that elements are made up of tiny particles called atoms.
That all atoms of a specific element are identical.
Atoms of different elements combine to form compounds.
Atoms are not created nor destroyed.
John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrödinger were all instrumental in the development of our understanding of the atom. Each of them made significant contributions to the atomic theory and the structure of the atom.
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.
Some key scientists in the historical development of the atom include Democritus (concept of "atomos"), John Dalton (atomic theory), J.J. Thomson (discovery of the electron), Ernest Rutherford (discovery of the nucleus), and Niels Bohr (Bohr model of the atom). Each of these scientists made significant contributions to our understanding of the atom and its structure.
This is one of John Dalton's four postulates in his Modern Atomic Theory of Matter.
The work of John Dalton is credited with being the beginning of modern atomic theory. In the early 19th century, Dalton proposed that all matter is composed of indivisible particles called atoms, each with its own unique properties. His atomic theory laid the foundation for our understanding of elements and compounds.
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.

John Dalton was one of the first men who theorized what the atom looks like(Dalton's Atomic Theory). And he also discovered that the pressure of 2 or more gases in one container can be known just by adding the individual pressures of each gases, we call it today as "Dalton's Rule of Partial Pressure", in honor of his brilliance!
John Dalton proposed his atomic theory in 1803, which included the idea that each type of matter is composed of one kind of atom. His work laid the foundation for modern chemistry by suggesting that atoms of different elements have distinct properties. Dalton's theory was instrumental in advancing the understanding of chemical composition and reactions.
Yes. He proposed that all elements have a specific mass, and each atom for a particular element would have that mass.
The idea that the atoms of different elements are different was first postulated by John Dalton in his atomic theory. In his theory he stated that all of the atoms of a given element are identical in mass and properities, and that compounds form by the combination of two or more different kinds of atoms.

I think it probably looked like a sphere. not positive.
The scientist who proposed that each element is made of a different type of atom is John Dalton. In the early 19th century, Dalton formulated the atomic theory, which stated that matter is composed of indivisible atoms, and each element has atoms that are unique in mass and properties. This foundational idea helped to advance the understanding of chemical reactions and the nature of elements.
Charlie Dalton was not a famous chemist. However his distant cousin John Dalton was. John Dalton did not have a periodic table to work with -- he did his work about 70 years too early for that. However, he did have a bit to do with elements and atoms. The name 'oxygen' means acid-maker. In Dalton's time chemists thought that every acid had to have oxygen in its formula. So he believed that what we now call hydrochloric acid, with formula HCl, contained oxygen in its formula. He therefore described an atom of this substance, which was then known as muriatic acid, as containing one atom each of hydrogen, oxygen, and 'muriatic radicle'. This 'muriatic radicle' was, in effect, an atom of chlorine from which an oxygen atom had been removed. A lot of futile effort was spent trying to remove the oxygen from chlorine gas to obtain this 'element' (but not by John Dalton).
