Greek Philospher Democritus, came up with the idea that all matter is made up of invisible elements. Democritus lived over a century. Democritus stated that Atoms could not split into smaller particles. Image by Jusepe de Ribera—The Bridgeman Art Library/Getty Images.

John Dalton conducted a theory that matter is composed from atoms of different weight and is mixed with different ratios, determined by weight. John Dalton has made a major contribution with his conepts and ideas to the Atomic structure , due to the fact of his amazing workings such as; the discovery of his Theory, which helped future scientist to improve and develop their own theories about the Atom.

Sir William Crookes created a cathode ray tube, which later on in his years became the basis of Television. WIlliam was one of the major factors of the development of Atomic Physics.

Pierre and Maric Curie made a concept that radioactive particlels break down Atoms, and release radiation. Marie's works were significant because she prepared the steps of the discovery for James Chadwick, of the Nuetron.

Joseph John Thomson discovers the Electron throught the Cathode rays properties. Through this discovery, enabled the Atomic structure to be able to create the link between negative charges and positive charges of atoms.

Albert Einstein, proposes new ideas about relatively, and guessed about the particle nature of light. Einstein created the formula E=mx2, which provided evidence to the of existence of Atoms.

Robert Milikan figured out the charge of an electron. Millikan's observations of Einsteins calculations proved Einstein's formula was correct, which developed Bohr and Einstien's further reaearch later on.

Ernest was born in New Zealand and attended the basis of his courses at the University of Cambridge (England). Ernest Rutherford disovered the theory of structuring a atom. Ernest is the major factor of the information on Radioactivity.

Niels Henrich constructed the bohr atomic model, with electrons travelling in orbits around the nucleous and chemical particles being determined by how many Electrons are present in the outer orbits. Neil attended the University of Copenhagen.

Henry Mosley discovered an atomic number of an element through study of an X-Ray Experiment. Henry Mosley used self built equipment to determine every element's identity is unfolded by the number of protons the elements has. Mosley created the world's first atomic battery.

Erwin Shrodinger created an equation to determine the possibility of finding how many electrons, at any given place surrounding the nucleus, called the wave equation.
