____________________ 1. The lowest energy level of an atom is the one farthest from the nucleus.

____________________ 2. If an electron gains energy, it may jump to a higher energy level.

____________________ 3. The area in an atom where an electron is likely to be found is called the electron cloud.

____________________ 4. The first energy level of an atom can hold two electrons.

____________________ 5. If an atom contains three electrons, then its second energy level would hold three electrons.

____________________ 6. Electrons cannot move from one energy level to another.

____________________ 7. A maximum of eight electrons can be held in the fourth energy level of an atom.

____________________ 8. Electrons are arranged in energy levels.

____________________ 9. The third energy level can hold up to 16 electrons.

____________________ 10. Electrons with higher energy are in the energy levels closest to the nucleus.
