-
The Alchemists broke the 4 elements down into the periodic table and stated the atomic theory. They did this by using the periodic table elements.
-
-
He theorized that all bodies are made of super small atoms which was a central figure to the atomic theory.
-
He theorized that atoms of matter come from the 5 fundamental solids. He also guessed that a fifth atom would come called ether.
-
Made by Nicolaus Copernicus
-
He defined the modern idea of an element and helped use experimentation to understand atoms and elements.
-
He determined oxygen was an essential substance in combustion. He was the father of modern chemistry and gave an element a name.
-
Had the theory of law of conservation of mass and constant composition with 4 parts to the theory. Also was the first complete time describing the matter in terms of atoms and their properties.
-
This was made by John Dalton
-
He hypothesized that equal volumes of different gases contain equal numbers of molecules with the same pressure and temperature.
-
He created the periodic classification of chemical elements. It was in an order of atomic weight.
-
This was made by Sir Joseph John Thomson
-
They discovered strong radioactive elements, radium and polonium. Marie forced radioactivity by certain atoms
-
He proved that atoms existed mathematically and helped revolutionize science through statistics.
-
He determined the magnitude of electrons charge and did it by measuring the oil drops that moved about.
-
He was known for pioneering states of radioactivity and the atom. The founded atoms consisted mostly of empty space
-
Neil purposed the theory for the hydrogen atom and the theory was based on the quantum theory
-
He experimented with ray tubes that showed how all atoms contain negatively charged particles or electrons.
-
He used self-built equipment to prove that every element is uniquely determined by the number of protons it has.
-
Made by Erwin Schrodinger
-
He discovered the neutron and this discovery led to the development of the atomic bombs.
-
He formulated quantum mechanics in terms of matrices. Also included discovering the uncertainty principle that stated a particles position and momentum cannot be known exactly.
-
He took Bohr atom model and helped describe a electrons certain position using mathematical equations.
