What to Focus On
- The nucleus contains more than 99.9% of the mass of an atom.
- Nuclear radius is about 10^4 times smaller than atomic radius.
- Nuclear volume is about 10^-12 of atomic volume.
- Isotopes: same Z, different A or N.
- Isobars: same A.
- Isotones: same N, different Z.
- Z = number of protons.
- N = number of neutrons.
- A = Z + N.
Common Mistakes to Avoid
All atoms of the same element have the same mass.
Proton, neutron, and nucleon mean the same thing.
