The ratio of the radii of hydrogen atom and its nucleus is ~ 10^5. Assuming the atom and the nucleus to be spherical,
(i). what will be the ratio of their sizes?
(ii). if atom is represented by planet earth, R_e = 6.4\times10^6m, estimate the size of the nucleus.
(i). Volume of the sphere =
Where, 'x' would be
Let R be the radius of the atom and r be that of the nucleus = R = 10^5r
Volume of the atom =
Volume of the nucleus =
Where, y and a would be respectively,
Ratio of the size of the atom to that of nucleus .
a.
b.
c.
(ii). If the atom is represented by the planet earth (R_e = 6.4\times10^6m), then the radius of the nucleus would be
X would be .
