|---|---|---|---|---|---|
| bohr model | electrons travel in definite orbits around the nucleus
🗑
|
||||
| quantum mechanical model | the behavior of electrons in atoms; modern atomic theory describes the electronic structure of the atom as the probability of finding electrons within certain regions of space; 90% probability of finding the electron in this space...
🗑
|
||||
| energy level | regions around the nucleus where the electrons are likely to be moving
🗑
|
||||
| quantum of energy | amount of energy needed to move an electron from the present energy level to the next higher one
🗑
|
||||
| atomic orbital | region of space where there is definitely a high probability of finding an electron
🗑
|
||||
| orbit | single path around something
🗑
|
||||
| orbital | region of space around the nucleus
🗑
|
||||
| aufbau principle | electrons enter orbitals of lowest energy level first
🗑
|
||||
| the pauli exclusion principle | an atomic orbital may describe at most two electrons
🗑
|
||||
| hund's rule | when electrons occupy orbitals of equal energy, one electron enters each orbital until all the orbitals contain one electron with parallel spins
🗑
|
||||
| heisenberg uncertainty principle | it is not possible to know both the velocity and the position of a particle at the same time
🗑
|
||||
| name electromagnetic radiation types | radio waves, micro waves, infared waves, visible light, ultra violet light, x-rays, gamma rays
🗑
|
||||
| longest wavelength of electromagnetic radiation? | radiowaves
🗑
|
||||
| name visible light | ROY G. BIV- red, orange, yellow, green, blue, indigo, violet
🗑
|
||||
| longest wavelength of visible light | red
🗑
|
||||
| shortest wavelength of visible light | violet
🗑
|
||||
| -\ ...(use your imagination!!!) | wavelength - meters (m)
🗑
|
||||
| `v` ... (you're not GT for nothing) | frequency - hertz (hz, 1/s, s^-1)
(s^-1 and 1/s called reciprocal second)
🗑
|
||||
| c | constant=speed of light - 3.00 x 10^8 m/s
🗑
|
||||
| atomic emission spectrum | pattern of frequencies obtained by passing a light emitted by atoms of an element in the gaseous state through a prism; the emission spectrum of each element is unique to that element
🗑
|
||||
| c= ? | -\ x `v`
🗑
|
||||
| h | planck's constant - 6.626 x 10^-34 J's
🗑
|
||||
| e | energy
🗑
|
||||
| e= ? | h x `v`
🗑
|
||||
| photons | a quantum of light, bundle of electromagnetic energy that behaves as a particle
🗑
|
||||
| mass of electron | 9.11 x 10^-28 g
🗑
|
||||
| photoelectric effect | electrons are ejected by certain metals when they absorb light with a frequency above a threshold frequency
🗑
|
||||
| photoelectric effect is seen ONLY when the frequency of light is above? | a threshold frequency
🗑
|
||||
| ground state | the lowest energy level occupied by an electron when an atom is in its most stable energy state
🗑
|
||||
| debroglie equation | -\= h/mv
🗑
|
||||
| m | mass
🗑
|
||||
| v | velocity
🗑
|
||||
| h (debroglie style) | kg x m^2/s^2
🗑
|
||||
| frequency (extra for al's need) | the number of wave cycles that pass a given point per unit of time; there is an inverse relationship b/w the frequency and wavelength of a wave... whatever that means
🗑
|
||||
| wavelength (another extra for al) | the distance between two adjacent crests of a wave... okay then what's a wave?!
🗑
|
||||
| wave (ANOTHER EXTRA BECAUSE THIS CRAP DOESN"T MAKE SENS) | wave is the method of travel for radiant energy; LIGHTBULB! wave's are roads that energy travels on, except really windy like around a mountain. screw chemistry teachers, I HAVE GOOGLE
