Marie & Pierre Curie -
discovered radium and
polonium - the rays she
theorized came from the
elements atomic structureJohn Dalton - identified the heredity
nature of red-green colorblindness
- proposed a theory that all matter
is made up of atoms that are invisible
and indestructibleJames Chadwick - discovered
neutrons - neutrons are located
in the center of an atomErnest Rutherford - discovered
nucleus of the atom
- demonstrated that the atom
has a tiny and heavy nucleusJ.J. Thomson - discovered electron
- realized that the acceptance
model of an atom did not account
for negatively or positively
charged particlesRobert Millikan - discovered
the study of elementary
electronic charge and the
photoelectric effect, the
electrons are what helps
atoms stick togetherJoseph Louis Proust - discovered
the law of constant compensation
in 1794, the law states that if a
compound is broken down the
masses will have the same
proportions regardless of the
original substanceNeils Bohr - proposed a
theory for the hydrogen
atom based on quantum
theory- stated that electrons
should move around the
nucleus only in prescribed
orbits.Michael Faraday - discovered
electromagnetic induction, he
believed that the atom had
more than just negatively
charged they had another
electrical componentErwin Schrodinger - his wave
equation is used to find the
allowed energy level of
quantum mechanical systems,
such as atomsAntoine Lavoisier - discovered
the role oxygen plays in
combustion, the first person
to make good use of balanceDemocritus - developed
concept of the ‘atom’ -
believed everything in the
universe was made up of
atoms
