This Danish physicist received a Nobel Prize in 1922 for his work in the understanding of the atomic structure and the creation of electron orbitals.
Neils Bohr
This man discovered the Law of Conservation of Matter that states matter is neither created nor destroyed.
Who is Lavoisier
In A.D. 1803 The Atomic Theory of Matter was stated with its 4 postulates.
Who is Dalton
JJ Thompson proposed this model out of a liquidy substance whose total positive charge cancelled out the charge of the electrons.
What is the Plumb Pudding model
This man is known as "The father of modern chemistry"
Who is Antoine Lavoisier
English Chemist and Physicist that created the first simplistic model of the atom
Who is Dalton
This scientist found that the mass of element 1 in one compound sample and the mass of element 1 in another compound sample are proportional.
Dalton
In 1897 this scientists did an experiment with a cathode ray tube to investigate charges of subatomic particles.
Who is JJ Thomson
Ernest Rutherford conducted an experiment where he discovered that the atom consisted of a dense, positively charged nucleus and negatively charged orbiting electrons. What was this model called?
The Planetary Model
This man is known as the father of the Nuclear Age because he found the nucleus.
Who is Ernest Rutherford?
On Janurary 1, 1801, this English chemist proposed that all elements are created from indestructible particles called atoms which are different from other element's atoms. Atoms are the same in same elements though. His theory also introduced compounds, which are made when different elements combine
Who is John Dalton
This scientist discovered platonium and radium and also died from radiation exposure
Who is Marie Curie
In 1896, this scientist discovered radiation.
Who is Henri Becquerel
Robert Millikan conducted an experiment with oil to measure what?
The mass of an electron.
The father of the electron
JJ Thomson
French scientist who studied fire to verify that matter is neither created nor destroyed
Who is Laviosier
This scientist created the Law of Definite Proportions that states compounds always have the same elements in the same proportion by mass.
Who is Joseph Proust
Who is Ernest Rutherford
Niels Bohr proposed an atomic model that explained how electrons didn't spiral into the nucleus, but orbit in different levels in the negatively charged electron cloud.
What is the Bohr Model
The father of modern atomic theory
John Dalton
French/Polish scientists that shared the Nobel Prize with Becquerel because of their discovery of radium and polonium.
Marie Curie
Ernest Rutherford discovered that ___(1)___ charged subatomic particles called ___(2)___ are found in the nucleus.
Positive and Protons
In 1914, this scientist stated that each atom has a different number of protons which is equal to the number of electrons in a electrically neutral atom, and that the mass is equal to the number of protons and neutrons.
Who is John Moseley
Erwin Schrodinger had a thought experiment where he would put a feline in a locked box and spray poisonous gas.
What is Schrodinger's cat
Father of quantum mechanics
Schrodinger/Heisenberg (Modern Scientists)
