Question

List the following types of electromagnetic radiation in order of increasing energy per photon. Radio waves, gamma rays, visible light, ultraviolet light, infrared radiation, microwaves, x-rays Two of the emission wavelengths in the hydrogen emission spectrum are 656 nm and 486 nm. One of these is due to the n = 4 to n = 2 transition, and the other is due to the n = 3 to n = 2 transition. Which wavelength corresponds to which transition? How many orbitals are in the following subshells? 1 orbitals 5 orbitals 3 orbitals What is the total electron capacity for each subshell? 2 e^- 10 e^-

Explanation / Answer

Q2.

higher energy --> shorter wavlength

therefore

n from 4 to 2 has larger energy than n form 3 to 2

therefore

486 nm --> 4 to 2 level drop

656 nm --> 3 to 2 level drop
