 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
