-
Turned simple metals into silver and gold. They believed substances, mind, philosophies, religion, magic, and astrology were all related
-
First to believe atoms were uniform. solid, hard, incompressible, and indestructible. He was also known as the "Laughing philosopher" since he was cheerful at work
-
he believed atoms broke down mathematically and set up the theory for Aristotle. He founded and taught at his school.
-
Proposed that elements are made of corpuscles of different chemical substances. He also created the idea of elements
-
Created the atomic model, and found total mass equals reactants in chemical reactions. He was eventually elected to French Academy of Science
-
First scientist to explain behavior of atoms in terms of weight. He started teaching when he was 12.
-
Dalton came up with this model since he believed atoms were the smallest particle
-
Discovered that equal volume and temperature equals the number of molecules, and that gasses are made of 2 atoms. He was the first to find the existence of molecules in the form of elements
-
Russian chemist who properly set up the current periodic table. He graduated with a gold medal from the Main Pedagogical Institute in Saint Petersburg
-
Physic from New Zealand who found radioactivity rose formation in gasses. And is known as father of nuclear physics.
-
Physic who discovered electrons in atoms. He concluded all matter was made up of "tiny corpuscles" now known as electrons.
-
Also known as the Bohr-model, named after the creator, Neil Bohr. The solar system model consists of a small nucleus surrounded by electrons.
-
French scientists who discovered radioactivity and its elements. They won the Nobel prize in 1903 and 1911.
-
Proposed by J.J Thompson and tries to explain electrons, and atoms with no charge.
-
Mathematically proved existence of atoms, and won the Nobel prize in 1921
-
Determined the magnitude of the electrons charged. And won the Nobel prize in 1923
-
Created the theory of placement of the electron, and won a Nobel prize the same time as Einstein
-
Showed the x-rays created by atoms, he created the chemical concept of the atomic number
-
Wrote the first mathematical equation to calculate energy levels of electrons in atoms. And was awarded the Nobel prize in 1933 for his discovery.
-
Model of atom that includes nucleus and electrons, this was made by Erwin Schrodinger
-
Formulated quantum mechanics in terms of matrices and terms. He discovered the "Uncertainty" principle. Which is particles position an momentum cannot be known exactly.
-
Discovered the Neutron Particle with no electrical charge. And won the Nobel prize in 1935
