|---|---|---|---|---|---|
| characteristic properties of all waves | frequency, wavelenght, speed, amplitude
🗑
|
||||
| at what speed to all electromagnetic waves travel in a vacuum | 3x10^8 m/s
🗑
|
||||
| continuous spectrum of white light | refracted into all colors
🗑
|
||||
| atomic emission spectrum | each element has a certain spectrum- certain wavelengths+frequencies- each element has its own unique line spectrum
🗑
|
||||
| 2 ways behavior of electrons can be described | waves and particles
🗑
|
||||
| waves formula | c= v times wavelength
🗑
|
||||
| particles formula | E=hv
🗑
|
||||
| Heisenberg's Uncertainty Principle | you cannot determine the position and momentum of an electron at the same time
🗑
|
||||
| 4 quantum numbers | principle qn, angular qn, magnetic qn, spin qn
🗑
|
||||
| 3 rules for writing electron configurations | Aufbau Principle, Poli exclusion principle, hund's rule
🗑
|
||||
| aufbau principle | electrons enter 1 at a time to the lowest energy orbitals until all electrons have been accounted for
🗑
|
||||
| pauli exclusion principle | an orbital can hold at most 2 electrons; 2 electrons must have different spins
🗑
|
||||
| hund's rule | electrons occupy equal energy orbitals so that a max # of unpaired electrons result- dont pair up until they have to
🗑
