The mean density of the nuclei is proportinal to:

Density of all the nuclei is same. Radius of nucleus is directly proportional to the cube root of mass number.

compare the radii of the nuclei of mass numbers 27 and 64 .

(i) What characteristic property of nuclear force explains the constancy of binding energy per nucleon (BE//A) in the range of mass number 'A' lying 30 lt A lt 170 ? (ii) Show that the density of nucleus over a wide range of nuclei is constant-independent of mass number A.

Nucleus of an atom resembles with a drop of liquid. Density of nucleus is very high, i.e., 10^(8) tonne/cc or 130 trillion tonnes m^(-3) . This density is about a trillion times greater than that of water. Density of nuclei of all elements are same, it is independent of atomic number or atomic mass. However, the radius of nucleus depends on the mass number . Surface However, the radius of nucleus depends on the mass number. Surface tension of nucleus is also very high. i.e., about 1.24 xx 10^(18) times, the suface tension of water. Ratio of volume of atom and nucleus is:
