Dalton’s atomic theory (article) | Khan Academy
Thanks to scientists such as John Dalton, modern chemists think of the world in terms of atoms. Even if we can’t see atoms with our naked eye, properties of matter such as color, phase (e.g., solid, liquid, gas), and even smell come from interactions on an atomic level. This article will discuss John Dalton’s atomic theory, which was the first complete attempt to describe all matter in terms of atoms and their properties.

Ancient Atomism – Stanford Encyclopedia of Philosophy
It has been suggested that Plato accepted time atoms, i.e., indivisible minima in time, but this is controversial. A treatise in the Aristotelian corpus probably not by Aristotle himself (On Indivisible Lines) addresses and refutes a number of arguments offered for the existence of indivisible lines, without naming their author. Plato’s student Xenocrates (396-314 BCE), third head of the Academy, is reported to believe in indivisible lines, and he may well be the target of the …

4.2: Indivisible – The Atomic Theory – Chemistry LibreTexts
One of the first people to propose atoms was a man known as Democritus. As an alternative to the beliefs of the Greek philosophers, he suggested that atomos, or atomon—tiny, indivisible, solid objects—make up all matter in the universe. Figure 4.2. 1: (left) Democritus by Hendrick ter Brugghen, 1628.

Who first said that atoms are indivisible? – Quora
Then whem Dalton discovered the things that we call atoms he assumed that that they are what Democritus was talking about. Nowadays we might suppose that quarks and leptons were a closer match to Democritus’ idea. So it is not as though we ever knew about atoms and someone said these things are indivisible. The idea of indivisible fundamental particles came first, and the atoms of the chemical elements were mistaken for them by people who were thinking more of the several kinds …

Who originally described atoms as small, indivisible spheres?
Well, basically his musings were purely on a philosophical basis, and he performed no experiments (so far as we know) on which he could base, and test his ideas. The very word atom, comes from the Greek, ατ oμos, which means uncuttable, or indivisible. Of course, we know now that the atom is NOT indivisible.

4.2: Indivisible- The Atomic Theory – Chemistry LibreTexts
The modern atomic theory, proposed about 1803 by the English chemist John Dalton (Figure 4.2. 1 ), is a fundamental concept that states that all elements are composed of atoms. Previously, we defined an atom as the smallest part of an element that maintains the identity of that element.

Is atom indivisible or divisible? – Reimagining Education
Why are atoms called indivisible? An atom is defined as the smallest individual particle of a matter. Atom was the indivisible particle up till Dalton’s theory. Then in 1897 when J J Thomson discovered electrons he stated that atoms are divisible. Then new subatomic particles proton, electron, and neutron were discovered so now atom is divisible.

Who believed that atoms were indivisible and indestructible?
On a final note: someone might look at this and conclude that since it’s the elementary particles that are indivisible, they should actually be considered the true atoms. You might think, we thought we had discovered atoms, but it turns out that we hadn’t yet, because there was still something smaller and more basic. So why don’t we change our terminology and call the elementary particles atoms, and find another word for the things that we have been calling atoms …

One of the tenets of Dalton’s and Democritus’ atomic theories stated that atoms are indivisible. Thomson’s discovery of electrons, which are subatomic particles, proved that atoms are not indivisible. Who said all atoms were indivisible and identical? 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 …
