The Quantum mechanical model of the Atom Light: electromagnetic radiation Waves: Amplitude of a wave is the distance from the center to the crest f a wve. This creast can be either a peak or trough Wavelength ( λ ) the distance b/w two consecutive crests Frequency ( ν ) the number of cycles that are completed in a second (Hz) λν =c (3.0*10^8) 1. Ultraviolet catastrophe 2. Photoelectric effect Bohr’s Model nucleus and electrons orbiting nucleus; electrons existed in stationary states-having a wave like behavior; the only way to lose or gain energy was to go from one stationary state to another. de Broglie proposed that electrons have wave-like particles; the wavelength is related to the velocity; the faster the electron is moving, the greater its kinetic energy. λ =h/mv Heisenberg uncertainty principle complimentary properties: the more you know about one, the less you know about the other (position and the velocity of electron), velocity related to wavelength nature of electron, position is related to particle
