Nuclear Radius and Density

• 1.4 fm

• 1.4 nm

• 1.4 mm

• 1.4 cm

Which of the following best describes the relationship between nuclear radius and density?

• The density increases as the radius increases.

• The density decreases as the radius increases.

• The density remains constant regardless of the radius.

• The density is inversely proportional to the square of the radius.

What factor primarily affects nuclear density?

• Temperature

• Pressure

• Nucleon number

• None of these

Why does nuclear density remain approximately constant across different nuclei?

• Because the volume and mass of a nucleus increase proportionally with the number of nucleons.

• Because the strong nuclear force varies with the size of the nucleus.

• Because the electron cloud density dictates the nuclear density.

• Because of the varying rates of nuclear decay.

What is the primary reason for using electron diffraction to determine nuclear radius instead of other methods?

• It is the most cost-effective method.

• It provides a direct measurement of the nucleus.

• It is the only method that can measure the radius of unstable isotopes.

• It can be performed at room temperature.

• 7.8 x 10^-15 m

• 6.3 x 10^-4 m

• 1.9 x 10^-15 m

If r₀ is 1.4 x 10^-15 m. What is the nucleon number of an atom with a radius of 6.3 x 10^-15?

• 91

• 72

• 56

How does the nuclear radius compare to the atomic radius?

• The nuclear radius is significantly larger than the atomic radius.

• The nuclear radius is about the same as the atomic radius.

• The nuclear radius is significantly smaller than the atomic radius.

• The nuclear radius increases with atomic radius at a linear rate.
