Question

Electrons are capable of emmiting engery in the form of light at very narrow ranges of wavelengths. these wavelengths can be measured to find the electrons?
A) mass
B) density
C) energy level
D) specific heat

Answer 1

C) energy level

Looking at quantum mechanics, we see that electrons exist at certain energy levels. When they get excited, they’ll jump from one energy state to a higher energy state and down. We can the. Look at the color it admits and determine what the energy level is.
