0:00
While researching a topic, a student has taken the following notes:
- Some atoms contain an excess of neutrons.
- Often, these neutrons form a “skin” on the atom’s surface.
- An atom of lead-208 has a neutron skin.
- The thickness of its neutron skin is approximately 0.28 trillionths of a millimeter.
The student wants to emphasize the thickness of lead-208’s neutron skin. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A.
The neutron skin surrounding an atom of lead-208 measures about 0.28 trillionths of a millimeter.
B.
Atoms with excess neutrons will often acquire a neutron skin.
C.
An atom of lead-208, like some other atoms, is surrounded by a neutron skin.
D.
Neutrons surround the surface of an atom of lead-208.
