Cathode Ray Tube Experiment - J. J. Thomson knew that charged particles could be deflected in a magnetic field. Discovering
electronsDemocritus- Believed all matter consisted of tiny indivisible particles made of all matterJ. J. Thomson- Discovered electronsJohn Dalton- Proposed atoms were identical,
atoms of a different element were different size.
and all matter is made of atomsPlum Pudding Model- Made by J. J. Thomson,
stated atoms were made of different pieces with
positive and negativr chargeNiels Bohr- Discovered atoms
transferred energy, electrons orbit
around the atomBohr Planetary Model- By Niels Bohr showed that
electrons and atoms are in orbit with differing
energyJames Chadwick- Discovered NeutronOil Drop Experiment- Using tiny drops of
oil between two metal plates to discover
the charge of electronsNeils Bohr- Discovered electrons in atoms orbit
the nucleusLaw of Conservation of Mass- Matter is neither
created of destroyedRutherford ModelErnest Rutherford - conducted the gold foil experimentPeriodi
Gold Foil Experiment- Ernest Rutherford
concluded atoms are mostly dense
space with a positive charge nucleusAntoine Lavoisier- Discovered Hydrogen and
OxygenRobert Millikan- Discovered charge of an electron
using oil drop experiementErwin Schrodinger- Found the likelihood of
finding an electron using equations
