Calculate the energy, in joules, required to excite a hydrogen atom by causing an electronic transition from the n = 1 to the n = 4 principal energy level. Recall that the energy levels of the H atom are given by E_n = -2.18 * 10^-18 J(1/n²) A)2.07 * 10^-29 J B)2.19 * 10⁵ J C)2.04 *10^-18 J D)3.27 * 10^-17 J E)2.25 * 10^-18 J

Quizplus · Accepted Answer

The energy required to excite a hydrogen atom from n=1 to n=4 can be calculated using the formula:
ΔE = E4 - E1 = -2.18 x 10^-18 J (1/4^2 - 1/1^2) = 2.04 x 10^-18 J

Therefore, the correct choice is C, which is closest to 2.04 x 10^-18 J.
