Question

An electron in Helium atom jumps from n2 to n1, find the energy and wavelength of emitted radiation ?​

Answer 1

Answer:

Where is this photon in the electromagnetic spectrum? -The wavelength of a photon emitted when an electron jumps from the n = 2 to n = 1 energy level of a singly ionized helium atom is 30.45 nm. On the electromagnetic spectrum, the photon would fall under the ultraviolet category.
