Document Summary
Light can act as both a wave and a paricle. Visible light-type of electromagneic radiaion; type of electron. Wavelength-( ) distance a wave travels in one cycle. Amplitude-weight of a wave crest or depth of a trough. Speed of light= c= (3x108) meters/second in a vacuum. C= (f: bohr model for drawing electron orbitals. When electron is removed, energy input is required (ionizaion energy: electron coniguraion. Inference patern of light=light acts as a wave s/d/p orbitals s=2 d=10 p=6: isoelectronic-elements made to look like other elements by adding or taking away electrons; negaive ionic charges have larger radiuses; more electrons relaive to protons=greater radius. Lewis dot structures: always follow octet rule, besides excepions (h=2, sf6=sulfur can hold from 10- 12, be and b can hold 4-6: resonance structure-diferent versions of same lewis structure. Polar vs. nonpolar: + side is less electronegaive, - is at most electronegaive atom: arrow faces more electronegaive atom.
