Chem Unit 4 quiz

what equation is used to find out possible l values from n

L<=n-1

a wave is characterized by its

wavelength (lambda), frequency v, and velocity and speed v

wavelength is

distance between two consecutive peaks in the wave (nm, m)

frequency is

the number of wavelengths that travel past a given point per second s-1 or hz

speed/velocity=

wavelength x frequency

amplitude

height of a wave from zero point, a can be +,0,-

intensity

the intensity of a wave, amplitude squared

higher energy is correlated with what

smaller wavelength, greater frequency, blue smaller energy

lower energy is correlated with what

larger lambda, smaller frequency, lower E

principle quantum #n describes

every orbit

ground state is what energy state

lowest energy state

excitation

energy transfers from lower to higher energy level absorbing photons

relaxation

energy goes from higher to lower energy level emitted photons

absolute value of change in e=

hv, or energy level in one photon

trident squared is

probability density

n=what

principal quantum #, describes the shell, energy level, orbital size, the bigger the n the bigger the orbital, n goes in front of the designation

how does n relate to the amount of orbitals a shell can hold

a shell can hold n2 orbitals

L=what

angular momentum, allowed values=0,1,n-1, specifies the subshell and indicates orbital shape

how to tell how many possible orbital values there are in a subshell

2L+1

ML=what

magnetic, values=-L,+10,L, specifies orbital within subshell, and orbital orientation

Ms=what

sprin, +1/2, -1/2, specifies electron spin state

Subshell options

s,p,d,f

L options

0,1,2,3

how to find max+of e- in subshell

each orbital can have 2 electrons per orbit max

how to find lambda

lamba=hc/absolute value of e change
