Atomic Nucleus Size
Atomic Nucleus Size
The nucleus of an atom is significantly smaller than the atom itself, roughly 10,000 times smaller in radius.
Nuclear Structure
Nuclear Structure
The nucleus, despite being tiny, is still structured and composed of smaller particles called nucleons.

Study Notes
Atomic Structure
- Atom's positive charge and mass are concentrated in the nucleus.
- Nucleus is significantly smaller than the atom (radius ratio ~10-4).
- Nucleus volume is approximately 10-12 times the atomic volume.
- Atom is largely empty space.
- Nucleus size comparison: a classroom-sized atom has a pinhead-sized nucleus.
- Nucleus contains almost all (over 99.9%) of the atom's mass.
- Nucleus has a structure composed of constituents.
- Nucleus constituent interactions hold it together.
Nuclear Properties and Phenomena
- Chapter will explore nuclear properties like size, mass, stability.
- Chapter will cover nuclear phenomena such as radioactivity, fission, and fusion.
