The Quantum Mechanical Model of the Atom
... In 1924, the Frenchman Louis de Broglie, a physics graduate student at the time, suggested that if waves can have particle-like properties as hypothesized by Planck, then perhaps particles can have some wave-like properties. This concept received some experimental support in 1937 when investigators ...

... ohr’s model of the atom gave us a first (though rough) picture of what an atom is like. It proposed explanations for why there is emission and absorption of light by atoms at only certain wavelengths. The wavelengths of the line spectra and the ionization energy for hydrogen (and one-electron ions) ...

In a few atomic beam experiments, separated arms have been achieved by using tightly collimated beams and material diffraction gratings. This has enabled precise measurements of electric polarizability [7, 8], phase shifts in at ...

CHEMISTRY 123-07 Midterm #1 – Answer key October 14, 2010
... Answer: Examine separately the amounts of a product generated from KO2 and H2O individually. Since the next question is about the quantity of O2, let us choose O2 as the product to study: 1. Mol amount of O2 from KO2: 0.25 mol KO2 x (3 mol O2/4 mol KO2) = 0.19 mol O2 2. Mol amount of O2 from H2O: 0. ...
