What is an alpha particle made of?
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
