John Dalton was probably the first to say that matter was made up of atoms with some kind of scientific basis for the statement. He even gave reasonably correct relative weights for several different kinds of atoms. Various philosophers had talked about atoms before, but without any sort of proof or experiments.

∙ 13y agoNo one invented the atoms. They have been in the world since it was made. In fact, the world consists of atoms! However, all the atoms are organized in something we call The Periodic Table, which was made by a man named Dmitrij Mendelejev.

Democritus said that in his opinion it could not; after a certain point one would arrive at a piece of matter that was atomos (Greek for indivisible). Well, he gave us a word to use later in the event that anyone found out that his opinion was correct, but he never knew if he was right or wrong. In 1803 the English chemist John Dalton was the first to come up with any evidence that there were such things as atoms, and he was able to show some of their properties. Most scientists accepted his theory as correct, although there were some diehards who maintained that it hadn't actually been proved right up until the beginning of the twentieth century. All of today's historians of science would credit Dalton with the discovery.

What was the alchemists view on atoms?
The alchemists were unaware that atoms even existed.
What evidence did Dalton have that atoms existed?
postulate
What was made fist molecules or atoms?
Atoms existed before molecules do. Without atoms, molecules could not happen.
Are atoms found in energy?
Yes, atoms are found in everything. From tables to plain air. So atoms are definitely found in energy. and anyway, electrons wrap themselves around atoms.
When do atoms combined?
They combine with other atoms when they form a molecule. They do so because the energy state of the molecule produced is less than the energy state that existed in the uncombined atoms.
What year did the electrons move in the atom?
They have always done that, ever since atoms and electrons existed.
When do compounds form?
when are atoms are more stable existed at a lower energy state in a combined form
Is there proof that the diprotodon existed?
They found fossils

Were our iron atoms produced before our sun existed?
Yes, Iron atoms were produced via fission in the core of an ancient star that has died. We are all stardust.
Is a selectron a fundamental particle found in atoms?
