began examining the atomic theory where they would treat different metals and oars to change the structure of an item. though this failed they did create the Scientific process which would allow for the eventual discovery of the atom. -
contributed to the atomic theory by saying that everything is made up into tiny bits which are called atoms. He further understood that different shapes of the atoms gave them different properties. This was a basic understanding of atoms. -
introduced the atomic theory in which ideal geometric forms served as atoms. According to this it said that atoms were broken down mathematically into triangles that formed into elements. -
discovered that atoms must exist based on the relationship between pressure and volume of gas. This was called the Boyles law that said that because they fixed mass of gas can be compressed gas must be made of particles or atoms. -
credited to be the first person to make use of the atomic theory. He also came up with the law of conservation. -
John Dalton came up with the idea that atoms were the smallest particles of matter and envision them as solid hard spears like billiard balls. -
created his own atomic theory saying that everything is composed of atoms which are invisible building blocks of matter and cannot be destroyed. -
came up with the idea that equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules. He also discovered that elements could exist as molecules instead of individual Atoms. -
found that when all non-chemical elements are arranged in order of increasing atomic weight the resulting table displayed in a reoccurring pattern. This was within groups of elements. -
created the discovery of the electron which is the negatively charged particle in the atom. -
came up with the atomic theory of matter and later discovered a new element isolate radium which had the ability to spontaneously disintegrate into other elements. This proves that the atoms of one element at least we’re not invisible. -
Thompson proposed the The plum pudding model which shows how electrons are surrounded by a volume of positively charged particles. -
was able to fully approved through the usage of evidence that Adams did indeed exist, and he was also able to demonstrate that the electrons could leave metal through usage of light. -
created a model describing the structure of atoms. This model describe the atom has a tiny, dense, positively charged core called a nucleus which the light, negative constitutes is called electrons, circulate at some distance -
thought that his cosmic ray photos were new Adams continuously being created to help prevent heat death. -
proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was one of the first to use the quantum theory. -
demonstrated that the major properties of an element are determined by the atomic number not by the atomic weight. Additionally he firmly establish relationships between atomic numbers and the charge of the atomic nucleus. -
was illustrated to show relative positions in motions of the planets and moons in the solar system. -
contributed to the atomic theory through formulating quantum mechanics in terms of matrix and discovering the uncertainty principle which states that a particles position and momentum can be both known exactly. -
was created by Erwin Schrödinger and Warner haisenberg. The model was a way to help visualize the most probable positions of electrons in an atom. -
worked on the wave particle theory coming up with an equation that treated the electrons of hydrogen atoms as a wave. This model worked on other elements and the equation is called the quantum mechanical model of the atom. -
discovered that the nucleus contain a particle called a neutron that carries no electric charge.
