Atomic Structure Project PT. 2

Aston has many eye opening discoveries and ones that added to those of others. He created the Aston Dark Space and was the first to develop the idea of Isotopes. He had evidence of two isotopes of the inner gas Neon and created a spectograph which allowed electromagnetics to mass the difference of the two isotopes to create seperation. Along with this he created the Whole Number Rule, which is still used today, that states all istopes have masses nearly to whole numbers. Due to these genius findings he recieved the Nobel Prize.

Aston (1919)

Bohr, just like many of his colleages, won the nobel prize due to his smarts. He wrote the theory of spectra and atomic constitution, and presented a picture of atomic structure that many still use today. He explained the properties of metals that helped add to the electron theory and showed a phyiscal representation that the liquid droplet theory in fact did help understand nuclear fission more. All of these are what got Bohr his Nobel prize and are very impressive due to the fact that they are still used today.

Among his many discoveries one was the uncertainty principle, which stated that errors cannot be ignored when in the atom scale due to how precise you need to be in order to be accurate. Along with this theory he also came up with the Theory in terms of matrix that said mechanical theories should have mathematical structures due to their complexity. His main success was based off of the quantum mechanics and the discovey of the allotropic hydrogen. After his main years of success he focused more on elementary particles and was later awarded the Nobel Prize.

This invention was named after its creators John Douglas Cockcroft and Ernest Walton. They created the particle Accelerator which was the first thing ever to perfrom a nuclear disintegration. This machines creates from High DC voltage to low AC voltage. This is still used today in things like x ray machines, televisions and photocopiers. Due to this invention both Cockcroft and Walton won a nobel prize.

Schrodinger addressed many problems concerning Thermodynamics. He set up theories with only waves, not waves and particles like seen with other scientists and discovered the orbit theory concerning the quantum condition. On top of these acheivements and new ways of looking at things he managed to snag a Nobel prize.

Paul Dirac was an ambitous man. He produced mathemathics equivalent to quantum mechanic equations but these were made of algebra. He also came up with the theory of holes which said a positive particle had the same mass as electrons. He created a wave equation that was opposite of Schrodingers and condicted his theory. On top of all that be published a book called Quantum Theory of the Electron. Due to these strong achivements he won a Nobel prize.

James Chadwick changed the game. He is the man who discovered the neautrons. He was able to demonstrate that radiation produced a continuous spectrum. On top of discovering Neautrons he anticipated that in the future neautrons would be used to help fight cancer. He worked with military to create atomic bombs and these advancements led to the awarding of Nobel Prize.

This team was one that created many advancements in the scientific field. They were the first to recognize that the uranium atom split when hit with neutrons, they were able to identify 10 different half life activites, and identify 16 different radioactive substances. On top of all this they recognized that Nuclear fission is what creates Barium. Due to these findings Hahn, 1/3 of the team, was awarded a Nobel Prize.

Seaborg, one of the later scientists, was a smart man. He was able to identify more than 100 isotopic elements and made it possible for other to predict radioactive charcteristics of isotopes. He also discovered transuranium elements and created the concept that demonstrated heavy elements and how they fit on the periodic table.

Fermi had many things named after him, mainly the Fermi statistics, which governed the fermions (also named after him). Besides these findings he also develped nuclear fission and discovered slow neautrons, a major advancement for atomic structure. He showed that nuclear transformations occur when neautons hit elements and won a noble prize for his findings. Due to this he is very important, just like his fellow atomic structure contributors.
