Unit 9

Electronic Orbitals

Demos to Prepare:
Springs and Waves
Spectra Tubes & Hippie Glasses

The Vectors of Electromagnetic Waves, Video:

Flame colors and electrical discharge in gases give the spectral lines from which we derive the orbitals of the electrons about the nucleus of the atoms. Video:

The lines of the spectra are the energy changes
when electrons drop from one orbital into another.

The probability of finding an electron about an atom.
