Document Summary
Electrons hold the key to understanding how atoms react and how molecules have structure. When atoms react, it is their outer pairs of electrons that interact. Our understanding of electronic structure comes from the study of light. Light is a wave-like electric and magnetic field. Wavelength- the distance between the point at the peaks (or any two points relative to one another on the other wave) The closer the waves are to one another, the smaller/shorter the wavelength is (and the higher the frequency) Speed of propagation- the speed/pace at which the wave is moving. Node- the half-way point (at the waves vertical center) Trough or valley- the lowest point of the wave. Wavelength and frequency (as one gets bigger the other gets smaller) Wavelength increases moving to the right ( ---> ) Frequency increases moving to the left (
