I Review | Constants | Periodic Table
The Rydberg equation expresses the wavelength,
of emitted light based on the initial and final energy
states (ny and ny ) of an electron in a hydrogen atom:
involving transition of the electron from two energy states ny to ng is given as
AE = -(2.18 x 10-18 J) × (
Ru x (금-)
Niels Bohr is credited with deriving this form of the Rydberg equation, which is sometimes called Bohr's equation.
where
RH = 1.097 x 10" m- 1.097 x 10-2 nm-1
You may also see this equation written as
Part B
=-Ry x
What is the change in energy, AE, in kilojoules per mole of hydrogen atoms for an electron transition from 7n-4 to n = 2?
Since
Express your answer
kilojoules per mole to three significant figures.

the two formulas are equivalent and sometimes used
interchangeably. It can help to remember that when
light is emitted, E is negative. When light is absorbed,
É is positive.
