Document Summary

It is decomposed to individual atoms in the gas phase: sample is placed in the graphite furnace c, light is passed through the atomic gas e, detector measures the intensity of the light light passes through a monochromator (separates individual wave lengths, x ray florescence (xrf) i. 6. 4 quantum mechanical model of the atom: bohr"s model of the atom, electrons move between allowed orbitals when they absorb or emit light, fixed orbital path (not correct, potential energy and orbitals (there are 4 different numbers that act like adresses and tell us where a specific electron is) i. ii. n: principle quantum number: corresponds to the rows of periodic table l: angular momentum number: corresponds to the shape of the orbital in space. It takes values from 0 to n 1 l=0 s l=1 p l=2 d l=3 f: m_l: magnetic quantum number: corresponds to the orientation of the orbital in space.
