Unit 2.2: Electron Configuration, EM Spectrum & Planck's Law   

Because every element has a unique electron configuration, every element produces a unique set of spectral lines.  It is these lines that allow scientists to identify the elements present in compounds and in the stars.  This unit studies the electron configurations unique to each element and the  frequency, wavelength and energy relationships of the Electromagnetic (EM) spectrum associated with the spectral lines resulting from these configurations.

 

TEKS:

C.6 The student knows and understands the historical development of atomic theory.  The student is expected to:

    C.6B   understand the electromagnetic spectrum and the mathematical relationships between energy, frequency, and wavelength of light

    C.6C   calculate the wavelength, frequency, and energy of light using Planck's constant and the speed of light

    C.6E express the arrangement of electrons in atoms through electron configurations and Lewis valence electron dot structures.
