Unformatted text preview: Successes of the Bohr model Niels Bohr (18851962) The electron in the hydrogen atom can have only certain discrete values of energy. Energy of the electron in the hydrogen atom is quantized . E n = 13.6 eV 1 n 2 WaveParticle Duality of Matter Louis de Broglie (18921987) h mu de Broglie reasoned that if light has particlelike properties, ``normal matter should also have wavelike properties. de Broglie derived an equation for the wavelength of material particles moving at constant speed: m is the mass of the particle and u is the speed.
