Key Concepts
• Bohr’s atomic model attributes hydrogen’s emission spectrum to electrons dropping from higher-energy to lower-energy orbits. ∆E = E higher-energy orbit - E lower-energy orbit = E photon = hν
• The de Broglie equation relates a particle’s wavelength to its mass, its velocity, and Planck’s constant. λ = h / mν
• The quantum mechanical model of the atom assumes that electrons have wave properties.
• Electrons occupy three-dimensional regions of space called atomic orbitals.
