History of the atom timeline caleb liu chemistry honors foley period 1 400 b.c. democritus' atomic theory greek philosopher democritus (460 b.c. 370 b.c.) was among the first to theorize the existence of atoms, which were indivisible and indestructible.

History Atoms Download Free Pdf Atoms Quantum Mechanics The atomic model has progressed over time based on contributions from scientists through experiments and theories: early greek philosophers proposed atoms as fundamental particles (democritus, 460 370 bc) dalton proposed atoms as indivisible spheres that combine in simple whole number ratios (1803) thomson's discovery of the electron led. Chloe boyd and neyha shankar atomic history timeline 1910 1926 robert millikan friedrich hund 1805 (discovery published) 1932 1925 c. 4th 5th century b.c.e.: 1913 john dalton wolfgang pauli 1898 james chadwick democritus neils bohr marie curie he accurately determined the charge. Aristotle (385 bc – 322 bc) • proposed that everything was made of four elements: earth, wind, fire, and water. • aristotle was believed over democritus because he was more popular and had a better reputation. democritus (460 bc – 370 bc) • the first scientist to theorize the atom. The document provides a history of discoveries related to the atom from ancient greek philosophers to modern quantum mechanics. it describes key contributors such as democritus proposing atoms, dalton establishing atomic theory, rutherford discovering the nucleus, bohr introducing quantum mechanics, and heisenberg establishing the uncertainty.

History of the atom with timeline free download as powerpoint presentation (.ppt), pdf file (.pdf), text file (.txt) or view presentation slides online. the document summarizes the history of atomic models from democritus' early atomic theory to niels bohr's 1913 model. The document outlines the history and characteristics of various chemical elements, starting with atoms and their formation into molecules. it details the properties, discovery dates, and significance of elements such as hydrogen, helium, lithium, and others, highlighting their roles in the universe and on earth. Democritus proposed the theory of matter, which stated that matter consists of invisible particles called atoms and a void. he also stated that all atoms differ in size, shape, position, and mass. in 1643 torricelli was able to invent the barometer, which would help measure the atmosphere. Democritus in 400 bc proposed that all matter is made of indivisible atoms that differ in shape and size. in the 1800s, dalton, dobereiner, and berzelius conducted experiments that provided evidence for the atomic theory. mendeleev organized the known elements into the first periodic table in 1869.
