The Visible Spectrum
5
Prisms
6
Continuous Spectrum Range of wavelengths with no missing colors (no gaps) Example: the complete visible spectrum
7
Line Spectra
8
Line Spectrum of Na and H2
9
Line Spectra Each element has a unique pattern of
lines / wavelengths / frequencies / colors!
10
Line Spectra
11
Electron Transitions
12
Atoms Emitting Light Each line corresponds to a different downward jump. The “larger” the jump, the shorter the wavelength of the photon produced
13
Atoms Absorbing Light Each line corresponds to a different upward jump. The “larger” the jump, the shorter the wavelength of the photon absorbed
14
The Quantum Mechanical Atom (Electron Density)
15
“s” Orbitals
16
“p” Orbitals
17
“p” Orbitals Come in sets of 3
18
“d” orbitals
