Question

what is the approximate value of the radius of a nucleus

Answer 1

1.75×10to the power of−15 m..........

Answer 2

• The radius of a nucleus varies with the atom it is present inside .

• Usually the nuclear radii ranges from 1-10 *$10^{-15}$m. This radius is much smaller than that of the atom, which is typically 10-10 m. Thus, the nucleus occupies an extremely small volume inside the atom.

• The radius of a nucleus is given by

                                     r = $r_{0}$ $A^{\frac{1}{3} }$ , where  $r_{0}$ =1.2 fm

                                                                  A= mass number of the nucleus

Substituting the values for  $r_{0}$ and A give us the radius of the nucleus .
