CHEM 201 – September 21, 2007 y λ = R((1/m 2 ) – (1/n 2 )) o m – shell that you are transitioning to o n – shell that you are transitioning from Atomic Spectra – result from excited atoms that emit light E = hν = hc/λ o h = 6.626x10 -34 J•s Einstein – proposed that light behaves like particles called photons Ψ is a wave function that describes where electrons are o Each wave function is defined by some variables Principal Quantum Number (n) – defines the size of the electron cloud and therefore the energy of the orbital (n=1, 2, 3, 4….) Angular Momentum QN (ℓ) – defines the shape of the orbital (ℓ = 0, 1, 2, 3,…) ℓ = 0 spherical, s-orbital

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
