In a model of the hydrogen atom, the energy levels Wn are given by the formula Wn = -Rn2, where n is an integer and R is a constant. Determine the energy released in the transition from n = 3 to n = 2.

A.

R5

B.

-R4

C.

5R36

D.

5R36

Correct answer is C

Given that W = -Rn2

from n = 3 to n = 2.

-R32 - (-R22)

-R9 - (-R4)

-R9 + R4;

with LCM 36

4R+9R36
