Democritus
460 - 370 BCE
Idea of the atom
Antoine Lavoisier
(1743-1794)
Proposed the Law of
Conversation of Mass
Joseph Proust
(1754-1826)
Proposed Law of Constant
Composition in 1799
John Dalton (1776-1844)
Proposed the Law of Multiple
Proportions
John Dalton (1776-1844) - Continued
1. The elements are made of atoms, which are tiny
particles, too small to see.
2. All atoms of a particular element are identical.
3. Atoms of different elements have different properties:
their masses are different, and their chemical reactions
are different.
4. Atoms cannot be created, destroyed or split.
5. In a chemical reaction, atoms link to one another, or
separate from one another.
6. Atoms combine in simple whole-number ratios to form
compounds.
J. J. Thomson (1856-1940)
Identified the negatively
charged electron in 1897
Marie Curie
(1867–1934)
1898
Discovered radioactive
elements
Robert Millikan
(1868-1953)
Determined the unit charge of
the electron in 1909.
Ernst Rutherford
(1871-1937)
1911 - Proposed the nuclear
atom
1920 - First referred to the
hydrogen nucleus as a proton
1920 - Proposed the
existence of the third atomic
particle, the neutron
Niels Bohr (1885–1962)
1913 - Electrons move around
the nucleus of the atom in
restricted orbits and explained
the manner in which the atom
absorbs and emits energy
Erwin Schrödinger
and
Werner Heisenberg
1926
Devise a quantum theory of
Non-Bohr Electron Cloud
James Chadwick
(1891-1974)
Discovered the neutron in
1932
Lise Meitner
(1878–1968)
1938
Meitner was part of the team
that discovered nuclear fission.
Peter Higgs
(1929 – )
1960s - Proposed the Higgs
Boson
Proven at CERN in 2012
