distance between successive crest of a wave
|
|
frequency |
how fast the wave oscillates up and down |
|
wave speed |
light that moves through space at a constant speed (c=3.00*10^8m/s) |
|
Uncertainty Principle (Heisenburg) |
You cannot 100% determine where the electron is/is going |
|
what does electron configuration tell us about the atom? |
the distribution among orbitals |
|
Aufbau principle |
You have to go from the lowest energy to the highest energy. Start at the bottom and make your way up.
|
|
Hund's Rule |
Fill each orbital seperately first, before going back and pairing up. |
|
Paulie's Exclusion Principle |
No 2 electrons in an atom can have identical quantum number |
|
Why do electrons occupy equal energy orbitals singly before beginning to pair up in two? |
repulsion forces of like charges |
|
Excited state |
when electrons jump up |
|
ground state |
when electrons are resting, are @ lowest energy |
|
valence electrons |
electrons s & p |
|
when can 2 electrons occupy the same orbital? |
if they have opposite spins |

|
what types of orbitals are in the third principle level? |
s, p, & d |
|
when does emission of light from an atom occur? |
when an electron drops from a higher to lower energy level |
|
what is the relationship between wavelength and frequency? |
llamda (h)= c/v or v= c/llamda(h) |
