Lesson Worksheet: Electron Energy Levels Physics
In this worksheet, we will practice determining whether an electron shell of an atom is filled and which electron transitions are possible in a given atom.
The diagram shows a hydrogen atom. The electron shown transitions between two energy levels of the atom.
Which energy level is the electron initially in?
- AThe first energy level
- BThe fourth energy level
- CThe second energy level
- DThe third energy level
Which energy level does the electron transition to?
- AThe second energy level
- BThe first energy level
- CThe third energy level
- DThe fourth energy level
The diagram shows a hydrogen atom. An electron, initially in the third energy level of the atom, transitions to the first energy level, emitting a particle at the same time. What kind of particle is emitted in this process?
- AA proton
- BAn electron
- CA neutron
- DA neutrino
- EA photon
Each of the following diagrams shows a hydrogen atom that is initially in an excited state. In each case, the electron transitions from a higher energy level to a lower energy level, emitting a photon. For which case is the energy of the emitted photon the greatest?
The diagram shows an electrically neutral neon atom. How many of the electrons in the atom are in excited states?
The diagram shows an electrically neutral atom. If one of the electrons in the innermost shell were to absorb a photon and move into an excited state, which of the electron shells shown in the diagram could it move to?
- AShell 2
- BShell 3
