Quantum concepts
Quantum Concepts

  • Bohr Atom

  • Light Quanta (particle-like waves)

  • Wave-like properties of particles

  • Wave-Particle Duality


Bohr model for hydrogen atom
Bohr model forHydrogen atom

  • Electron (-q) rev. around proton (+q)

  • Coulomb force, F = q2/4peor2, q = 1.6E-19 Coul, eo=8.854E-14Fd/cm

  • Quantization L = mvr = nh/2p, h =6.625E-34J-sec


Bohr model for the H atom (cont.)

  • En= -(mq4)/[8eo2h2n2] ~ -13.6 eV/n2

  • rn= [n2eoh2]/[pmq2] ~ 0.05 nm = 1/2 Ao

    for n=1, ground state


Bohr model for the h atom cont

En= - (mq4)/[8eo2h2n2] ~ -13.6 eV/n2 *

rn= [n2eoh2]/[pmq2] ~ 0.05 nm = 1/2 Ao *

*for n=1, ground state


Energy Quanta for Light

  • Photoelectric Effect:

  • Tmax is the energy of the electron emitted from a material surface when light of frequency f is incident.

  • fo, frequency for zero KE, mat’l spec.

  • h is Planck’s (a universal) constant h = 6.625E-34 J-sec
