This energy-level diagram depicts energy being absorbed or emitted by electrons undergoing electron transitions.
Part 1
Which of the arrows in the energy-level diagram represent absorption of energy and which represent emission of energy?
Homework Answers
When an electron present in the lower energy level (ground state) excites to the higher energy level (excited state) absorption of energy takes place and when an electron present in the higher energy level comes to the lower energy level emission of energy takes place.
1 . Absorption of energy : arrows d,e,f
Emission of energy : arrows a,b,c
2. Higher the energy absorbed or emitted, lower is the wavelength and vice versa.
Arrow c in the diagram represents the emission of light with longest wavelength
3. The arrow e represents the absorption of light in an excited state.
4. The arrows b, f represent transitions involving the greatest energy change

In an atom, an electron jumps from an energy level of n = 5 to an energy level of n = 2. During this process, a photon was emitted by the atom. a photon was absorbed by the atom. a proton was emitted by the atom. a proton was absorbed by the atom. Now, compare the energy either emitted or absorbed by the atom in Scenario 1 to the energy emitted or absorbed in Scenario 2. An electron jumps from...
