List Of Equations

Postby inlovewithchemistry » Mon Oct 15, 2018 11:45 am

Does anyone have a helpful list of equations that pertain to this unit? I've been trying to compile one, but lose track of units and constants. If anyone could post a complete list (with labeled constants), that would be very helpful!
Thank you!

E = hν (h=6.626 x 10^34 Js)
c = λν (c=3.00 x 10^8 m/s)
E(photon) - E(energy to remove e-) = E (excess) = EK(e-) = (mv^2)/2
E(n) = -(hR)/(n^2) (R = 3.29 x 10^15 s^-1)
λ = h/p
∆p ∆x ≥ h/4pi

I might be missing a few but most of these are on Outline 2 that is posted on the class website.

Speed of light, c=λv, c=3.00*10^8
Momentum, p=mv
Energy, E=pv
Wavelength, lambda λ
Planck's Constant, h=6.626 x 10^-34 joule*seconds
Bohr Frequency Condition, ΔE=hv
E(photon)=threshold energy-Ek
En=-hR/n^2
Rydberg constant: R=3.29*10^15Hz
Difference in energy levels, ΔE=E(final)-E(initial)
De Broglie: λ=h/p
Heisenberg's Indeterminacy Equation: (Δp)(Δx)≥h/4π
