Development of Atomic Theory Timeline

The development of atomic theory has been a gradual process, with many key milestones along the way.

• Scientist:Democritus
• Year:400 B.C.
• Discovery:Proposed that all matter is made up of tiny, indivisible particles called atoms.
• Impact:Introduced the concept of atoms, but his ideas were not widely accepted.

• Scientist:John Dalton
• Year:1803
• Discovery:Developed the atomic theory, which stated that all matter is composed of atoms, atoms are indivisible and indestructible, and all atoms of a given element are identical in mass and other properties.
• Impact:Established the foundation of modern atomic theory.

• Scientist:J.J. Thomson
• Year:1897
• Discovery:Discovered the electron, a negatively charged particle within atoms.
• Impact:Led to the discovery of subatomic particles and the “plum pudding” model of the atom.

• Scientist:Ernest Rutherford
• Year:1911
• Discovery:Conducted the gold foil experiment, which led to the discovery of the atomic nucleus.
• Impact:Revolutionized the understanding of atomic structure and led to the development of the nuclear model of the atom.

• Scientist:Niels Bohr
• Year:1913
• Discovery:Proposed the Bohr model of the atom, which described electrons orbiting the nucleus in specific energy levels.
• Impact:Introduced the concept of energy levels and quantum mechanics in atomic theory.

• Scientist:Erwin Schrödinger
• Year:1926
• Discovery:Developed the quantum mechanical model of the atom, which uses wave functions to describe the behavior of electrons.
• Impact:Provided a more accurate and sophisticated understanding of atomic structure.
