Question | Answer |
Wavespeed equation | speed = length x frequency |
What was the double slit experiment | 2 slits made in an object,, 2 wave propogations created when electrons shot through, showed interference pattern |
what did the double slit experiment prove | light and electrons act as waves |
what is the photolelectric effect | electrons emitted from any surface when light of a high enough frequency shines on that surface |
what did the photoelectric effect prove | light acts as a wave and a particle |
define line emission spectrum | light shines through a prism produces a series of different frequencies that make up that light |
what happenes when light hits an atom | electrons get absorb energy and go up a level, then releases E as certain wavelengths of light and goes back |
difference between photoelectric effect and excited state | pe = electron gets so excited it flies away excited = electron just goes up an orbital |
define principal quantam number. what is it equal to? | the main energy that the electron is in. |
formula for number of electrons per E level | 2n^2 |
define angular quantam number | is the shape of the orbital (like p or s) |
define magnetic quantam number | orientation of the orbital |
define spin quantam number | tells whether electron spin is clockwise or counterclockwise |
Define heisenberg uncertainty principle | impossible to determine the position and velocity of an electron at the same time |
define aufbau principal | an electron occupies lowest E level it can and fills from the bottom up |
define hunds rule | if there are 2 or more empty orbitals of the same E level, each orbital takes one electron before subshell orbitals fill with second electron |
what is electronegativity | E it takes to add an electron to atom |
what is electron affinity | E released when neutral atom gets an electron |
define pauli exclusion principle | each orbital can hold max of 3 electrons with opposite spin |
