The Discovery Of The Atom - 1384 Words

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry s a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons. There are many Scientist that contributed in the investigation of the atom which are: 1- John Dalton 2- Sir William Crookes 3- Wilhelm Rontgen 4- J.J Thomson 5- Max Planck 6- Albert Einstein 7- Ernest Rutherford 8- Neils Bohr 9- James Chadwick 10-Otto Hahn The Discovery of the Atom first came from the Greeks which made a theory â€Å"The idea that all matter is made up of tiny, indivisible particles, or atoms, is believed to have originated with the Greek philosopher Leucippus of Miletus and his student Democritus of Abdera in the 5th century B.C. (The word atom comes from the Greek word atomos, which means â€Å"indivisible.†)† (InfoPlease Atomic theory) After that theory scientists started Wondering about this theory and a lot of Scientists made up Models and conducted Experiments to Explain this Theory. In this report we will put our self’s inside Each scientist’s Shoe and see What has he discovered.

The long process of solving the mysteries of matter has involved numerous scientists and their experiments, which have ushered in modern knowledge of the subject and countless innovations in science using the knowledge of matter s properties. The atom makes up nearly everything humankind knows of; therefore, it has significant effect on everything people make.

Reaching its pivotal point of advancement during WW2, as Einsteins work was finally put into practice as scientists from the U.S detonate the first nuclear weapon, which unintentionally, later ushers in a cold war. After the cold war, the development of nuclear power leads to serious complications as several units fail, making people questionRead MoreHistory And Science Of The Atom1507 Words   |  7 PagesHistory of the Atom By Karina Vazquez Period: 4 May 11, 2016 Mr.Sanchez Chemistry B The atom is an important thing in the world of science and chemistry. The atom might have started on a different point of view on how the atom works. There were many different people who had many good and different ideas on how to use the atom and what it was used for. Democritus was one of many other philosopher and scientists that wanted to start the discovery of the atom.

Over 30 different scientists have added on the development of atomic theory, and made science changing discoveries that are still today quite impressive, even in comparison to modern day scientists. There are countless scientists involved in the evolution of atomic theory, but less than 50 have majorly impacted the way we view atomic theory today.

This theory was based on the concept that any given item in the universe could be broken down using pico- and femtometer atomic/subatomic/alpha particles. If this idea had never been composed, science would have suffered as a result and many scientists would not have beenRead MoreDmitri Mendeleev: The Development of the Periodic Table Essay1529 Words   |  7 Pagesother progress. Discoveries that led to the creation of Mendeleev’s table of elements: It was only possible, however, for Mendeleev’s table to be created and thus progress to the form in which we know it now due to the efforts of various other scientists in discovering information that changed the theory around the atom. The discoveries of the atom and the means to derive atomic weight led to Mendeleev’s ability to create the periodic table, and it is further research into the atom that has led toRead MoreEssay on Ernest Rutherford and The Gold Foil Experiment 755 Words   |  4 Pagesfamously known for â€Å"splitting the atom.† His work on the gold foil experiment contributed greatly to the model of the atom and helped develop the standard model of the atom to what we now use today. Without his contributions we would still be using the Plum Pudding model, an out dated and incorrect model, and we would have less of an understanding of how atoms form the world around us. Before Rutherford’s Geiger-Marsden experiment the most popular model of the atom was the â€Å"plum pudding model† developedRead MoreJ.J. Thomson1052 Words   |  5 Pagestime of his discovery many other scientists were working on the same thing (Joseph John Thomson). He was doing a lot of research on the nature of electric discharge in a high-vacuum cathode-ray tube. The ray’s deflection by electrically charged particles brought Thomson to the realization that there are much smaller particles of matter than just atoms (Morgan). At the tome of his discovery he called the â€Å"particles† corpuscles, and theorized that they may make up, or reside inside of atoms. People wereRead MoreAtom History Essay960 Words   |  4 PagesAtom History Essay An Atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electrons. The Atom was theorized by a man named Democritus of Abdera, Thrace in between c.a 460 BC - ca. 370 B.C. Atom is derived from the Greek word â€Å"atomos† , which means to be uncuttable. He had a theory that everything is composed of â€Å"atoms†, which he believed that these minuscule objects are indivisible, indestructible and have and always been in motionRead MoreHistory Of An Atom.

However, still to this day, not one human has seen what an atom looks like. Our current atomic model, the same one in which you most likely learnt in 5th grade, is really just an educated theory, comprised of years of experimental trials and errors. In fact, the ‘original’ four elements, introduced by ancient philosopher Aristotle: Fire Air, Water, and
