Q 30.27: The nucleus of the hydrogen atom has a radius of about 1.2 x 10-15 m. The electron is normally at a distance of about 5.3 x 10-11 m. Assume that the hydrogen atom is a uniform sphere of radius 5.3 x 10-11 m. What percentage of the volume of the atom is occupied by the nucleus?

Respuesta :

Answer:

[tex]1.1606\times 10^{-12} \%[/tex] is the percentage of the volume of the atom is occupied by the nucleus.

Explanation:

Radius of the nucleus of the hydrogen atom,[tex]r_n=1.2\times 10^{-15} m[/tex]

Radius of the hydrogen atom = [tex]r=5.3\times 10^{-11} m[/tex]

Volume of hydrogen atom ,V= [tex]\frac{4}{3}\pi r^3[/tex]

[tex]V=\frac{4}{3}\pi r^3[/tex]

Volume of nucleus of hydrogen atom , [tex]V_n=\frac{4}{3}\pi r_{n}^3[/tex]

[tex]V_n=\frac{4}{3}\pi r_{n}^3[/tex]

Percentage of the volume of the atom is occupied by the nucleus:

[tex]\frac{V_n}{V}\times 100[/tex]

[tex]\frac{\frac{4}{3}\pi r_{n}^3}{\frac{4}{3}\pi r^3}\times 100[/tex]

[tex]=1.1606\times 10^{-12} \%[/tex]

[tex]1.1606\times 10^{-12} \%[/tex] is the percentage of the volume of the atom is occupied by the nucleus.
