Answer to Question #243265 in General Chemistry for bekah

Question

When electrons move from one electronic energy level to another, a specific amount of energy is either absorbed or emitted, depending on the direction of the transition.

Calculate the wavelength of the photons emitted by hydrogen atoms when they undergo transitions from n = 4 to n = 3.

Answer 1

The hydrogen atom emitted light, meaning that that the electron must come from a higher energy level to a lower energy level. The wavelength of the light emitted is 434 nm.
