Question

Determine the energy change associated with the transition from n = 4 to n = 1 in the hydrogen atom.Group of answer choices:3.27 × 10-17 J4.62 × 10-19 J2.04 × 10-18 J1.64 × 10-18 J6.54 × 10-18 J

Answer 1

• The energy change associated with the transition from n = 4 to n = 1 in the hydrogen atom can be calculated as follows :,

∆E = RH ( 1/nf -1/ni)

{where nf = 1 andni = 4 ( (n final) is the level you end up at, and (n initial) is the one you started from.)}

So, ∆E = RH ( 1/nf -1/ni) = (-2.18 * 10^-18 J)( 1/4 -1/1)

= 2.04375 X 10^-18 J of energy is emitted.

Therefore , option C is the correct answer.
