Chem. Chapter 7

vocab for Ch. 7

QuestionAnswer
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
