-While Erwin Schrödinger found the protons inside that nucleus, James Chadwick discovered that there were also neutrons.
-He still used the "Quantum Mechanical Model", just added neutrons in the nucleus in 1932.
-He found has theory by using polonium as a source of neutrons, he bombarded wax. The German physicist Werner Heisenberg showed that the neutron could not be an electron-proton pair, and was actually a new elementary particle.
-He had many other accomplishments including that he was held in a German prison camp for all of World War 1, he led the British team in the Manhattan Project, in which the UK and Canada supported the USA's World War 2 effort to build the world's first nuclear bomb.

-He established the "Quantum Mechanical Model" in the 1920s
-He used mathematical equations to describe the likelihood of finding an electron in a certain position.
-He believed that the electrons just orbited around the nucleus. He felt as if instead over time that were sporadic and formed an object. He named them orbitals. He believed they did not go around the nucleus in perfect circles.
-He did experiments by formulating the wave equation and revealed the identity of his development of the formalism and matrix mechanics.
-His biggest accomplishment was his theory along with getting a Nobel Prize. ]]> 2019-10-20 15:04:52 UTC https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984755 Niels Bohr-1913 laurenpaul https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984756 -Bohr was born October 7, 1885 in Copenhagen, Denmark.
-He claimed that the electrons were not placed randomly in 1913.
-Called his model the "Bohr Model".
-He believed that they had distinctive spots in an orbit, just like planets in a solar system.
-Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. This is how he tried proving his theory.
-Another accomplishment he had was e was on of the main physicists to form the first ever atomic bomb during World War II. ]]> 2019-10-20 15:04:52 UTC https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984756 Ernest Rutherford-1911 laurenpaul https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984757 -He was born August 30, 1871, Brightwater, New Zealand
-He was a New Zealand-born British physicist who came to be known as the father of nuclear physics.
-He discovered that all atoms have a nucleus in 1911, calling in the "Nuclear Model".
-All the protons attract to the center.
-Rutherford's Gold Foil Experiment proved the existence of a small massive center to atoms, which would later be known as the nucleus of an atom
-Other accomplishments include that he invented an early detector of radio waves, and he discovered alpha and beta radioactivity.]]> 2019-10-20 15:04:52 UTC https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984757 JJ Thomson-1904 laurenpaul https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984758 -Thomson was born on December 18, 1856 in Cheetham Hill, Manchester, United Kingdom.
-He established the "Plum Pudding Model" in 1904
-He said that the atoms were not indivisible, there were electrons
-He claimed there would be a positively charged substance, and in that substance there would be electrons throughout.
-He did experiments with cathode ray tubes showing that all atoms contain tiny negatively charged subatomic particles or electrons.
-He also found Cathode Rays, which are beams of light that follow an electrical discharge in a high-vacuum tube.]]> 2019-10-20 15:04:52 UTC https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984758 John Dalton-1803 laurenpaul https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984759 -He was born on September 6, 1766 in Eaglesfield, United Kingdom.
-Claimed that matter is made up of indivisible atoms.
-Also said that atoms combine to make different compounds.
-Other accomplishments of John Dalton includes his several remarkable meteorological observations in his first published work, and he published the first ever paper on color blindness
-He used gases to do experiments to conduct his theory.
-He founded his theory in 1803.

-He worked alongside his teacher Leucippus.
-He kept cutting bread in half repeatedly until he no longer could. As a result he called the bread he could know longer cut "atomos" which means uncuttable. This is where the word atom comes from.
-He felt as if this bread, or any object, was filled with these particles called atoms.
-He believed that were all different shapes and sizes.
-He even believed iron particles had hooks on them, and that was the reason it was so strong
-Also claimed that these particles were never deleted, just moved or exchanged
-Democritus and Leucippus were never scientists, so they were never able to do experiments that would prove anything
-Everyone believed the philosopher Aristotle]]> 2019-10-20 15:04:52 UTC https://padlet.com/laurenpaul/pfpklldfe4is/wish/399984760 Pictures of Scientists laurenpaul https://padlet.com/laurenpaul/pfpklldfe4is/wish/399997722 https://live.staticflickr.com/4890/31847384198_fe21365c7d_b.jpg
