Plato was the first person to develop the concept of an atom. He was also a philosopher and metephysicist. -
He came up with the theory that everything in the world is made up of tiny particles called atomos. He was also a philosopher in ancient Greece. -
The Alchemists made a scientific process that would allow for the eventual discovery of the atom. The Alchemists also invented lots of lab equipment. -
Robert Boyle was the first to argue the four element theory. He was also a philosopher and an inventor. -
Antoine Lavoisier developed the law of conservation of mass. He was a French nobleman. -
John Dalton is considered the father of the atomic theory. He discovered that only like atoms in a mixture of gases repel one another, and that atoms of different elements very in size and mass. -
The Billiard Ball model was created by John Dalton. The model was one of the first models of an atom and was proposed as a ball like structure. -
He discovered that an equal volume of gases contains equal numbers of molecules and that elemental gases are composed of two atoms. He was also a mathematician. -
He invented the Periodic Table of Elements. He has an element named after him called Mendelevium. -
He discovered that the atom consists of smaller sub particles called electrons. He entered college at 14. -
They hypothesized that radioactive particles cause atoms to break down and release radiation. Marie was a physicist, chemist, and pioneer in the study of radiation. -
The Plum Pudding Model was made by J.J. Thompson. the Plum Pudding model showed an atom is a sphere of uniformly distributed positive charges with electrons imbedded in regular pattern. -
Albert Einstein mathematically proved the existence of atoms. He also helped build the Atomic Bomb. -
He did experiments to determine the electrical charge carried by a single electron. He did the famous oil drop experiment. -
He made the Rutherford model which was a model of the atom. He also determined that there are two types of radiation. -
Niels Bohr was a Danish physicist. He discovered that the atom consists of a nucleus and electrons. -
He created Moseley's law characterized concerning x-rays that are produced by atoms. He also fought in WWI. -
The solar system model was made by Niels Bohr. The Bohr Model has an atom consisting of a small, positively charged nucleus orbited by negatively charged electrons. -
He created a powerful model of the atom. He also discovered Schrödinger's wave equation. -
The Electron Cloud Model was created by Erwin Schrödinger. The model predicts the likely position of the location of the electron based on a function of probabilities. -
He discovered the neutron. He also won a Nobel prize for discovering the neutron.
