 Heinsberg Uncertainty principle It is impossible to determine both position and veolocity of an electron or any other particle at the same time Schrodinger wave equation give a probability of finding an electron and its velocity at a given place around the nucleus Principal Quantum number n, all possible values, indicates main energy level occupied by the elctron shell total number of orbitals in a shell n^2 Angular Momentum Quantum number l, indicates shape of orbital, diff shapes l=0->l=n-1 Magnetic Quantum numb m, orientation, Spin number s +-.5 DeBroglie matter exhibits wave-like properties (dual particle-wave) nature Characteristics of waves Interference: interaction of waves travelling thru the same medium Diffraction:Bending of waves Characteristics of Particles 1)Photo electric effect 2)Emission of light by hot objects Speed of light 3*10^8 m/s visible spectrum 400-700 nm wavelt llamada, distance between crests (tops),troghs(bottoms) frequency numb of waves that pass a given pt per second (V thing) speed emr how fast a given peak is moving thru space Planck (add on) said quantized nrg e=hv h= constant Alpitude distance from middle of wave to peak Hz one wave/s photo electric effect emission of electrons from a metal when lite shines on it. Afbau's Principle Electrons tend to occupy the lowest lvs first Hund's Rule Pairing of electrons in the orbitals of the same energy does not occur until every orbital of the SAME energy has at least 1 electron Pauli Exclusion Principle No 2 electrons within an atom can have all 4 quantun numbers the same
