Atomic Line Spectra

Atomic Line Spectra and the Electron Shell Transitions they represent

Atomic Line Spectra and the Electron Shell Transitions they represent - put another way

Working with the Rydberg Equation

1/λ = R(1/S² – 1/L²)

λ: Wavelength (m)

R: Rydberg Constant

R = 1.097 x 10⁷ m^-1

S: Series Number

L: Line Number

L > S

Bohr Model of the Atom

mheducation Bohr Model Energy Changes Applet

E = -hCR/n2

h: Planck’s Constant

h = 6.626 x 10-34 m2kgs-1

c: Speed of Light in a vacuum

c = 3.00 x 108 ms-1

R: Rydberg Constant

R = 1.097 x 107 m-1

n: Electron Shell Number
