|
4
He 2 |
|
|
What is a beta particle made of?
|
0
e -1 |
|
|
What is a photon?
|
small particle that makes up light energy whose energy is directly proportion to their frequency
|
|
|
What do ν, Hz, λ, c, h represent respectively?
|
v = nu represents frequency (the # of wavepeaks that pass per period of time). Usually expressed in Hz = reciprocal seconds.
λ = lambda represents wavelength. (m) c = speed of light (m/s) h = Planck's constant (J*s) |
|
|
Equation relating wavelength to frequency?
|
wavelength(λ) x frequency(v) = (c)speed of light
|
|
|
E =
|
(Planck's constant)h * (frequency)v
OR (Planck's constant)h * (lightspeed)c / (wavelength)λ |
|
|
Quantum numbers:
|
n - principal quantum number (positive integer), represents the shell
l - angular-momentum quantum number (0 to n-1), defines 3D shape of orbital or the subshell (0=s,1=p,2=d,3=f...) m(l) - magnetic quantum number (-l to +l), defines spatial orientations of the orbital |
