1. Waves

2. The Electromagnetic Spectrum

3. The Electromagnetic Spectrum

4. 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

19. Neon Electronic Structure
