Question

Quizplus · Accepted Answer

The energy change associated with the transition from n_i to n_f in a hydrogen atom is given by the formula ΔE = -2.18 × 10^-18 J (1/n_f^2 - 1/n_i^2). Substituting n_i = 2 and n_f = 5 gives ΔE = -4.58 × 10^-19 J, which is option C. Only the energy change (not the sign) is asked for in the question, so the negative sign is ignored.
