Document Summary

Energy = (-2. 18 x 10^-18) /n^2 n is an arbitrary quantum number (integer) The only way to detect where an electron is is by interacting it with electromagnetic radiation changes position and properties of electron. Tells us about the momentum if you try to locate the position of an electron, it will gain velocity and move away. Momentum goes up as you put an electron to a nucleus. Electron particle in atom is best thought of as a wave. Particles have wave-like character have wavelength. = h/p only significant when lamda is comparable with the size of the object (confine electron in the dimensions of an atom) The schrodinger wave equation yields wavefunctions where quantum #s arise naturally. 3 quantum numbers: defines size and shape of the orbital. *interrelated values n- principle; determines energy and size (1, 2, 3 ) l- azimuthal; determines shape (0, 1, 2, n-1) Ml- magnetic quantum number; determines spacial orientation (-l l )
