Atomic Theory 4

- Schrodinger
- Energy for the system
- Wow Mr.Schrodinger! Did you just come up with that equation? Explain me your thinking.
- Wave equation
- Hψ=Eψ
- wave function
- Of course! This equation can be solved to yield a series of wave functions, each of which can be associated with an electron binding energy! The letters might represent electrons binding energy, while the signs represents the probability of finding an electron in a given region of the atom
- So revolutionary!
- Schrodinger
- waves containing electrons
- Nucleus containing positive matter
- With my model, there are only certain allowable states or energies that an electron in an atom can have, which is similar to a standing wave.So basically the behavior of atoms can be explained by treating them mathematically with my equation.
- Schrodinger
- Present Day TIme. . .
- Do you agree with me saying that Schrodinger is still the most accurate representation of an Atom?
- Yes. Both his atomic model and theory shows that electrons don't move around the nucleus in orbits, but in clouds where their position is unclear.
-
- To show that electrons orbited around the nucleus in waves instead of set paths, Schrodinger formulated a wave equation that accurately calculated the energy levels of electrons in atoms.
- James Chadwick
- Science Lab
- Periodic Table
- Neutrons
- Protons
- Electrons
- Hmm. This seems like the neutrons of an atom. The neutrons seem to only affect the mass and not the charge. The element that these uncharged particles are located in is Beryllium according to my calculations.
- After creating his equation, Schrodinger was able to develop his quantum mechanical model of an atom. This was the first of its kind and explained why moving electrons emitted energy when moving closer to the nucleus.
- James Chadwick
- Nucleus containing protons and neutrons
- Electrons
- No, It's my newly revised model. Here, neutrons are particles with no electrical charge and that they only affect the mass. In other words, they are neutral particles that lie withing the nucleus.
- Today, Schrodinger's Atomic model is still widely accepted as the most accurate model of an atom..
- James Chadwick
- Haha! Now that I know that radiation is composed of particles with a neutral electric charge, I will finally be able to create a atomic bomb to destroy the world!!! No one will stop me from spilting the nuclei of atoms into two using neutrons.
- In 1932, Chadwick conducted an experiment in which he bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. This led to his discovery of the neutron
- Bombarded Beryllium
- Cambridge University, 1932
- Beryllium has 4 protons 5 neutrons and 4 electrons. I can see 5 neutrons through my microscope so this material must contain that element.
- Chadwick was able to solve the mass problem that Bohr had with his model and theory by discovering the neutron. He then revised Bohr's model with neutrons
- Is that Bohr's Atomic Model.Mr.Chadwick?
- Chadwick's discovery of the neutron was pivotal to the discovery of nuclear fission, and ultimately the development of the atomic bomb.
- J. Robert Oppenheimer
- Did someone just say atomic bomb? Come to America and we'll fund and assist with the atomic bomb
- Is that guy crazy. Why is he saying his thoughts out loud?
- Idk man.
