During the period of 400 B.C (which was a long long time ago) Democritus proposed that matter is formed into pieces that could not be cut into smaller parts. He called these smallest possible pieces "atomos", which means uncuttable. An atom is the smallest particle of an element in modern terms. He started the whole idea of an atom.

Who coined the word atom?
The Greeks, from the word atomon, meaning "uncuttable, indivisible."
Who was the greek philosopher who made a mental model of the Atom?
Democritus was the Greek philosopher who made a mental model of the atom. He said that atoms composed everything and were physically but not geometrically indivisible. Between the atoms there is empty space. They always will have been, and will be in motion and are indestructible. Different atoms differ in size and shape.
Who was the first greek philosipher who discovered an atom?
The first Greek philosopher to propose the concept of an atom was Democritus. He believed that all matter is composed of tiny, indivisible particles called atoms. Democritus's ideas laid the foundation for the development of modern atomic theory.
What does the model of Democritus' look like?
Democritus proposed that all matter is comprised of tiny, indivisible particles called atoms that are constantly moving. He believed that atoms have different shapes and sizes, and that they combine and separate to create different substances. His model did not have any experimental evidence to support it at the time, but it laid the foundation for modern atomic theory.
Scientist that contributed to the history of the atom in order?
Democritus proposed the concept of atoms as indivisible particles. John Dalton introduced the atomic theory, stating that elements are composed of atoms. J.J. Thomson discovered the electron, leading to the plum pudding model of the atom. Ernest Rutherford conducted the gold foil experiment, leading to the nuclear model of the atom. Niels Bohr developed the planetary model of the atom with distinct energy levels.

Explination of democritus model?
what year was the democritus model made?
What major changes occurred from Democritus's model to Thomson's model?
Democritus proposed the first atomic theory, suggesting that matter is made up of indivisible particles called atoms. Thomson's model, proposed in the late 19th century, introduced the idea of the atom as a sphere with embedded electrons, challenging the indivisibility of atoms seen in Democritus's model and suggesting the presence of subatomic particles. Thomson's model also laid the groundwork for the later development of the more accurate planetary model of the atom by Rutherford.
Who were the scientists that were responsible for creating the atom model?
the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!
