Atomic History

100

I am most known popularly for my cat example, but am known in chemistry circles for my wave-function which predicted the probable location of an electron around an atom as well as the shape of an orbital.

Erwin Schrödinger

I am the name of the Chemist who theorized that much like light, electrons two have a dual-particle wave nature.

Louis DeBroglie

300

Niels Bohr discovered that electrons can only exist at certain defined distances/energy levels away from the nucleus.  This led to 3D shells that an electron could possibly exist in which are called  _____?

Orbitals

I am the name of the high-energy thing that Ernest Rutherford shot at a thin sheet of gold foil, which led to the eventual discovery of the nucleus and that the atom is mostly empty space.

Alpha Particle

I am the letter for an orbital which is shaped like two perpendicular dumbells.  My quantum number is l=2

D-Orbital
