Antoine Lavoisier discovered the Law of Conservation of  Matter. This was the theory that matter could not be created nor be destroyed. He is also known for naming elements such as Hydrogen, Oxygen, and Carbon. He discovered that when Hydrogen and Oxygen come together, they form a compound (water). After multiple experiments, he also concluded that respiration was just another form of combustion. http://www.famousscientists.org/antoine-lavoisier/ and https://quizlet.com/7001524/atomic-theory-scientists-and-their-contributions-flash-cards/ and http://famousbiologists.org/wp-content/uploads/2013/06/antoine-lavoisier.jpg

Robert Millikan is most commonly known for his oil-drop experiment. After conducting this experiment, he reached the conclusion of electrons having a charge. With this, he was also able to figure out the mass of one electron. He did this by using the formula, 9.11x10^-28g. These findings led him to the discovery of cosmic radiation. Besides being a famous scientist, Millikan is also an author. In 1923, Millikan won the Nobel Peace Prize.

Discovered by Erwin Schrodinger,  it was found that electrons are located based upon the amount of energy they carry. Electrons with a high amount of energy are found farther away from the nucleus than electrons with a minimal amount of energy.

Niels Bohr, a Danish scientist, conducted an experiment where he took electrons and placed them at certain energy levels. In his theory, Bohr stated that electrons are constantly moving around the nucleus. He was later proved wrong. Electrons do NOT orbit the nucleus. In the Wave Model it is not possible to tell where electrons are located.

John Dalton, an English chemist, is most commonly recognized by many due to his theory of the atom. He conducted many experiments before he could explain his theory. This theory contained information pertaining to the in-destruction of atoms and what they make up (elements). Also, the fact that two or more atoms make up compounds. This theory would later become the "foundation of modern chemistry." http://isimabomba.free.fr/biographies/chimistes/dalton.jpg and https://docs.google.com/presentation/d/1Zu1pMqIK1-8-qJWNarYUHprYECrJvPBVULCDGseazZM/edit#slide=id.p51

Moseley was an English physicist who was influenced by Rutherford. Rutherford took in Moseley as something like an intern. Moseley found a flaw in the periodic table since it was positioned according to the atoms weight and chemical properties, the weight and chemical properties did not always match up. He asked if it was possible that elements could have more fundamental property than atomic weight? Moseley put together an experiment to shoot high-energy electrons at different chemical elements. He discovered each element had a unique frequency. Moseley concluded that if the positively charge in the nucleus increased by just one then the element would change. The periodic table was then arranged by the number of positive charges in the nucleus. Website Citation.

Rutherford was an English physicist, he was heavily interested in one of his experiments called the "Gold Foil Experiment" that has to do with the structure of atoms. The experiment was firing a stream of tiny positive particles at a sheet of thin gold foil (approximately 2000 atoms thick). His observations were that most of the positive particles fired passed right through the gold atoms of the gold foil, but some bounced away. He knew that positive charges repel positive charges. He found that this meant the gold atoms in the sheet were open space. He concluded that the one small part of the atom was a dense, positively charged center that he later called the "nucleus". All the atoms positively charged particles live in the nucleus. Citation.

Thomson, an English Scientist, provided the first indication that atoms were made of smaller parts. Thomson conducted an experiment testing the passage of an electrical current through a gas, he found that is had more of a negative charge. Thomson concluded that the atom is divisible, he discovered electrons but he never could find the positively charged "smaller particles" (protons). Citation
He proposed the "Plum Pudding" model which is a model of an atom. Since atoms were made with a positively charged particle and electrons the smaller particles are like raisins in pudding.

Democritus was a Greek philosopher who wanted an answer to the question; Could matter be divided forever or is there a limit? His idea was that matter could not be divided forever, eventually the smallest piece would obtained. He named the smallest piece atomos meaning "not to be cut". Citation.
