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
En = –2.18 × 10–18 J(1/n2)
◦ 2.07 × 10–29 J
◦ 2.25 × 10–18 J
◦ 2.04 × 10–18 J
◦ 3.27 × 10–17 J
◦ 2.19 × 105 J
