|---|---|---|---|---|---|
| wavelength (l) | distance between identical points on successive waves
🗑
|
||||
| frequency | number of waves that pass a given point per unit time
🗑
|
||||
| amplitude | height measured from the center of a wave, the squared of the amplitude gives the intensity
🗑
|
||||
| speed | wavelength multiplied by its frequency in reciprocal seconds
🗑
|
||||
| photon | particle of light
🗑
|
||||
| atomic spectra | results from excited atoms emitting light
🗑
|
||||
| line spectra | results from electron transitions between specific energy levels
🗑
|
||||
| quantum numbers | n,l,m
🗑
|
||||
| n | pricipal quantum number: positive integer: number of last orbital
🗑
|
||||
| l | angular momentum: find by s=0, p=1, d=2, f=3
🗑
|
||||
| m(l) | magnetic momentum: what it is asking for in its orbital diagram
🗑
|
||||
| m(s) | negative or positive 1/2: depends on where it falls in the orbital diagram
🗑
|
||||
| s orbital | spherical in shape, radius of shere increases with increasing value of n
🗑
|
||||
| p orbitals | have two lobes with a node between them
🗑
|
||||
| d orbitals | four of the five orbitals have 4 lobes; the other resembles a p orbital with a doughnut around the center
🗑
