Discovery of the Atom Timeline YouTube
It wasn't until 1803 that the English chemist John Dalton started to develop a more scientific definition of the atom. He drew on the ideas of the Ancient Greeks in describing atoms as small, hard spheres that are indivisible, and that atoms of a given element are identical to each other.

The structure of atoms is somehow related to electricity. (p.95) Discovered atoms have negative particles (electrons) using a cathode ray tube. Discovered electron's charge to mass ratio: 1.76 x 108 C/g. (p. 97-98) Thomson's Plum Pudding Model, 1900.

A History of the Atom Theories and Models
In 1803, John Dalton presented his atomic theory based on three key ideas: Matter is made of atoms which are tiny particles that cannot be created, destroyed, or divided Atoms of the same element are identical, and atoms of different elements are different Different atoms combine together to form new substances

Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a chemical change. An element consists of only one type of atom, which has a mass that is characteristic of the element and is the same for all atoms of that element (Figure \(\PageIndex{1}\)). A macroscopic sample.
Atomic models timeline by Daenna González Issuu
Dalton's atomic theory stated that different elements were made of different atoms, but did not explain what made the atoms different. The answer is that atoms are composed of subatomic particles, protons, neutron, and electrons, and the number of the protons and electrons in an atom defines the element it represents.

Atomic model, in physics, a model used to describe the structure and makeup of an atom. Atomic models have gone through many changes over time, evolving as necessary to fit experimental data. For a more in-depth discussion of the history of atomic models, see atom: development of atomic theory.

Early History of the Atom Matter is composed of indivisible building blocks. This idea was recorded as early as the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word "atom" is derived from this term.
Atomic Theory Timeline
Greek philosopher Democritus. Atomic theory originated as a philosophical concept in ancient India and Greece. The word "atom" comes from the ancient Greek word atomos, which means indivisible. According to atomism, matter consists of discrete particles. However, the theory was one of many explanations for matter and wasn't based on empirical data.
