Basics of Chemistry
the building blocks of matter
atoms
the name used for both neutrons and protons
nucleons
the two qualities of matter
inertia, takes up space
this Greek philosopher believed atoms had the same properties as the materials they made up (ie water atoms were slippery and cold)
Democritus
The scientist who performed the Gold Foil Experiment
Ernest Rutherford
the subatomic particle with a negative charge
electron
the cloud like space around the nucleus where electrons fly around
orbital
the tendency of an object to resist acceleration
inertia
this scientist believed atoms were solid balls. he had 5 principles which were mostly correct
John Dalton
J. J. Thomson's atomic model
Plum Pudding model
the subatomic particle with a positive charge
protons
this is formed when two or more atoms are chemically bonded
molecule
the measure of how much space something takes up
volume
The scientist who discovered electrons by using the Cathode Ray Tube
J. J. Thomson
the scientist who determined the charge on electrons
Robert Millikan
the neutral subatomic particle
neutron
a ___________ molecule is made up of two atoms of the same element bonded together
diatomic
inertia is measured by measuring this
mass
the scientist who discovered protons
Ernest Rutherford
Robert Millikan's experiment
Oil Drop Experiment
these two subatomic particles have nearly equal masses
neutrons and protons
all atoms want to (increase/decrease) energy
decrease
__________ properties determine what type of reaction a substance can undergo
chemical
the scientist who discovered neutrons
James Chadwick
The scientist who contributed to the development of the atomic bomb, and who was so anxious about the possibility of the atomic bomb being used that he had to take sleeping pills for the rest of his life
James Chadwick
