-
The Alchemists found a substance that made silver or gold with more common elements. -
Introduced the atomic theory with atoms were ideal geometric figures. -
Theorized that unsplit table small atoms made all materials in bodies. -
Published the Scopticel about how all matter is composed of important particles from which all materials are constructed. -
Found out the reactants and the total mass of products in a chemical reaction is always the same. -
Theorized that all matter was made of atoms, indestructible building blocks, and were indivisible. Different elements were made of different sized and mass. -
Didn't show any nucleus or electrons and defined an atom to be a ball like structure. -
Proved the arrangement of elements in the order of their increasing atomic weights. -
Found out that electrons charge was always a multiple of precisely determined charges. -
Theorized that tiny negatively charged subatomic electrons or particles were found in atoms. -
Theorized one of the reason atoms break down are radioactive particles. -
Discovered the existence of the element's radium and polonium. -
Was made to explain two properties of the atom. -
Einstein helped revolutionize science through the use of statics and probability by mathematically proving atoms exist. -
Proposed an atomic structure thing that said the inner orbit of an atomic held less electrons than the outside. -
Showed hoe the electrons orbit about the nucleus at different distances. -
Proposed that the number of positive charges in the atomic nucleus is the atomic number. -
Proposed that nearly all of an atom is empty space, so when alpha particles go through the empty space the nucleus has a very little reaction. -
Predicts the likely location of the electron based on a fraction of probability. -
Created the first electron cloud model. -
Discovered the Neutron in atoms. -
Discovered that elements were not only found in individual atoms but instead be found in molecules.
