The atomic theory that was widely accepted for about 2,000 years was proposed by the ancient Greek philosopher Democritus. He theorized that matter is composed of small, indivisible particles called atoms, which vary in shape and size. However, this idea was largely overshadowed by Aristotle's rejection of atomism, favoring the concept of continuous matter. It wasn't until the 19th century that John Dalton revived and refined atomic theory based on experimental evidence.
The exact date that John Dalton stated his theories about the atom is unknown. However, it is believed that he first stated his theory sometime between 1800 and 1803.
Democritus' atomic theory states that atoms are indivisible. That's why they have their name. Atoms is a plural of atom. Atom derives from Atoms. Atoms is greek for INDIVISIBLE. His theory states that atoms cannot be divided any further.
John Dalton: In the late 1700s, John Dalton developed the atomic theory on which all current understandings are based.

The model of the atom based on Quantum Theory is often called the "Quantum Mechanical Model" or the "Quantum Model." This model describes the behavior of electrons around the nucleus as probabilistic, rather than in fixed orbits.

This supposition is the basis of the atomic theory, beginning 2 500 years ago.

The idea of the atom was first proposed by the ancient Greek philosopher Democritus in the 5th century BC. He believed that everything is made up of tiny, indivisible particles called atoms.
of course Dalton's atomic theory is still believed today. but it has some defects, like his first postulate states that an atom is indivisible. but as you know its not correct. but the 4th and 5th postulate of his were exactly correct and are still the basis today. for a better answer please check on wikipedia.
In 335 BCE, Aristotle opened his school, Lucem. He did not believe the Atomic theory and therefore taught his students that all substances were not made up of atoms but something smaller. He believed that everything was made up of small amounts of fire, water, earth and air.
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
